Which process is responsible for the loss of biomass at each level of the ecosystem
Answer:
The correct answer is - excretion
Explanation:
In any ecosystem, there is a loss of biomass and energy at each level of the energy pyramid or trophic level. Biomass and energy both lost due to completing the life processes.
All the biomass is eaten at each level as not all food they take completely digested and removed by the process of excretion in various forms such as solid feces, carbon dioxide, and water in respiration and water and urea in urine.

-Gross Primary productivity
-Biomass
-Net Primary productivity
0r
-Primary productivity
2. Suppose a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. What could be assumed about the level of available organic matter in the mouse versus the plant?
-There will be less organic matter available.
-There will be more organic matter available.
-Organic matter does not transfer between the plant and the mouse.

0r
-carbon dioxide
5. Why are there less secondary consumers in an ecosystem than producers?
-Around 90% of energy from one trophic level to the next is available.
-There is less land to use for habitat after the producers grow.
-More tertiary consumers will eat secondary consumers over producers.
0r
-There isn’t enough energy available to support more secondary consumers.
...Thanks...
Answer: 1. Net primary productivity
2. there will be less organic matter available
3. it decreases
4. ethanol
5. there isn’t enough energy available to support secondary consumers
Explanation:
1. Gross Primary productivity is the organic material that is left after subtracting energy used for respiration. It is always greater than net primary productivity.
2. There will be less organic matter available for the mouse because plant is a primary producer of biomass and it lies at the lowest trophic level as we go up in the trophic level the level of energy reduces.
3. The biomass will decrease while going from lower to higher trophic levels this is because of the fact that the plants or other autotrophs are the primary producers of biomass.
4. The incomplete combustion of gasoline and methane are the major fuels contributing to global warming.
5. There are less secondary consumers in an ecosystem because more tertiary consumers are dependent on secondary consumers for their food and energy requirements.

D. 100% will show the phenotype of the dominant allele and 0% will show the
phenotype of the recessive allele.
Answer:
C. 75% will show the phenotype of the dominant allele and 25% will show the
phenotype of the recessive allele
Explanation:
on the punnet square you can see that 3/4=75/100 of the individuals have the dominant allele so they will manifest the dominant phenotype the other 25% don't have the dominant allele
75% will show the phenotype of the dominant allele and 25% will show the phenotype of the recessive allele.
What is Punnett square?An illustration of the potential genotypes of an offspring resulting from a specific cross or breeding event is called a Punnett square. Knowing the parents' genetic make-up is necessary to create a Punnett square. They have tabular representations of the different conceivable combinations of their gametes.
The underlying presumption is that different qualities assort independently from one another and that each feature is determined by a single gene locus. There are numerous exceptions, even if this is generally true for many beneficial qualities, particularly when picking characters for plant or animal breeding.
This device was developed in the 20th century, many years after Mendel's groundbreaking genetics experiments.
Therefore, 75% will show the phenotype of the dominant allele and 25% will show the phenotype of the recessive allele.

Which behavior is an example of how animal communication helps a population survive?
A. A bird destroys another bird's nest so that it can nest in that spot.
B. Giraffes and zebras compete for water at the same watering hole.
C. Ants use their bodies to form a bridge that other ants can use to get to food.
D. A bee returns to the hive and shares the location of food with other bees.
Answer: The correct option is D.
A bee returns to the hive and shares the location of food with other bees.
Explanation:
This is because animal communication is the interaction or sharing of information that occur between animals of the same species. It is how animals commune in a language they will understand. A bee returns to the hive and shares the location of food with other bees is a behavior of animal communication that help population to survive because, the bee share information to other bees which is beneficial to them and aid they to survive as we know that food is an essential for survival.

Using the Gizmo, find a carbon atom path from the atmosphere to the cement plant. (Hint:
One of the ingredients in cement is limestone.)
Path:
Answer:
Path: Atmosphere -> Ocean -> Shells -> Limestone -> Cement Plant
The path of a carbon atom is - air, ocean, shells/coral reef, limestone, cement plant.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron, and other ingredients.
Common components used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace, silica sand, and iron ore.Limestone form the coral reefs that are massive structures deposited by coral polyps.Coral reefs get their carbonate from the ocean that comes from air Carbon in limestone is produced in a cement plant when heated to make calcium oxide. The waste product is carbon dioxide.Thus, the path of a carbon atom is - air, ocean, shells/coral reef, limestone, cement plant.

Answer:
equation is 2n = 46
Explanation:
humans have 2 sets of 23 chromosomes
Two full sets of chromosomes make up a diploid cell. Humans mostly have diploid cells, which have 23 pairs of chromosomes each, for a total of 46 chromosomes.
What are chromosomes?There are 22 pairs of autosomes and two sex chromosomes in this. The person received one copy of each pair of chromosomes from their mother and the other copy from their father.
A "diploid cell" is one that has two copies of each chromosome; human somatic cells are diploid and have 46 chromosomes, 22 pairs of autosomes, and a pair of sex chromosomes.
Histones, which function as packing proteins for the majority of eukaryotic chromosomes, join forces with chaperone proteins to attach to and compress the DNA molecule, maintaining the integrity of the molecule.
Therefore, diploid cells, have 23 pairs of chromosomes each, for a total of 46 chromosomes.

Clouds with light rain.
In your current location, the weather is much like this picture: cloudy and drizzly. The weather has been like this for several days. The good news is that the weather report says warmer weather is coming soon.
Which type of front most likely caused this weather?
occluded front
stationary front
warm front
cold front
Warm fronts move more slowly and are less violent than cold fronts. They are associated with warm air moving over cold air and are more likely to produce large regions of light to moderate rain, drizzle or snow. Cirrus clouds and alto cumulus, along with fog, often precede warm fronts as they move through an area. The milder weather that follows will be warmer in temperature. So it would be warm fronts.
Answer:
Warm Front

Table salt and table sugar, examine the chemical formulas for salt and sugar. What do they tell you about what type of bonding is present in each compound
Answer:
Explanation:
Table salt, also NaCl (sodium chloride) is an ionic compound in which there is a transfer of an electron from the sodium atom to the chlorine atom. This electron transfer is characteristic of an ionic/electrovalent combination/bonding. While table sugar, also C₁₂H₂₂O₁₁ (sucrose) is an organic compound; thus has covalent bond within it's carbon chain, carbon-hydrogen bond and carbon-oxygen bond. Covalent bonding involves the sharing of electrons between two atoms, these electrons that are shared are referred to as "shared pair".
