According to this food web, which of the following organisms do hawks eat?
Snakes and squirrels
Wolves and mushrooms
Grasshoppers and wolves
Squirrels and mushrooms
Answer:
snakes and squirrels
Explanation:
According to this food web, hawks eat the organisms like Snakes and squirrels. Thus, the correct option is A.
What is the Food web?The food web may be defined as the interconnection of a large number of the food chain with one another and forming a web-like pattern.
In a food web, one organism can hold more than one position. In other words, it is a series of branching lines rather than a straight line. The flow of energy is very difficult to calculate in the food web.
Hawks are the tertiary consumers that eat toads, snakes, squirrels, etc. So, hawks are carnivore organisms. Because of being the tertiary consumers, they significantly depend on secondary consumers.
Mushrooms are decomposers. So, options B and D are eliminated. Option C contains grasshoppers that feed on the grass directly. So, they are primary consumers in the food web.
Therefore, according to this food web, hawks eat the organisms like Snakes and squirrels. Thus, the correct option is A.

Explain your observations on what organisms need to grow. Explain how human activity can impact an organism’s ability to obtain the resources it needs to survive. State your opinion about how human activity can be changed to have less impact on the lives of other organisms.
Answer:
All living organisms need food, water, and shelter in order to grow and survive. Human activities can have a lot of impacts on different organisms; whether they’re good or bad. Humans may take away natural habitats for some by expanding into a previously untouched area. In the same sense, they might end up accidentally providing a food or water source. Although there is some good, humans should limit and change their activities in order to have a less impact on the lives of other organisms. We could create more national or state parks, which would make a safe haven for a lot of organisms. We could impose stricter punishments for people for litter as it harms organisms. We might create nature preserves in order to force humans to leave alone the other organisms in a certain area. Overall, we play a big role in a lot of different organisms lives and we need to make sure it’s a positive one.
Hope this helped, all written by me so no plagiarism(:
Explanation:
Human activity is a major threat to the planet's biodiversity. This is because human population growth thus far has been exponential, meaning that its growth rate stays the same regardless of population size. This makes the population grow faster and faster as it gets larger.
Populations may grow exponentially for some period, but they ultimately reach a carrying capacity when they become limited by resource availability. Humans, however, have continued to work around carrying capacity as they develop new technologies to help support the ever-growing population. This threatens biodiversity because the more humans there are, the more this displaces other species and reduces species richness. Human-mediated causes of biodiversity loss. Deforestation for resource mining or urbanization can displace native organisms. Deforestation for resource mining or urbanization can displace native organisms.

Explanation:
Answer:
Organisms are generally much different from their ancestors in the fossil record.
Explanation:
Today organisms are generally different from their ancestors in the fossil records because of the concept of evolution.
Evolution has caused ancient organisms to change drastically from their present day cohorts.
Although, some similarities exists and they can help tell how the organisms have evolved, nonetheless, ancient life forms are much different. Paleontologists use evidence from a diverse source to interpret fossils in order to show relationships between organisms.match the descriptions to the photos

In science class, Blaine’s teacher puts one glow stick in a cup of hot water and another glow stick in a cup of cold water. She asks the students to think about how the temperature of the water will affect the chemical reaction that occurs inside the glow stick once it is bent and starts to glow.
Which glow stick will be brighter once it is bent? Explain your answer.
Answer:
The glow stick that was in the cup of hot water will be brighter once it is bent. The production of more light is evidence that the chemical reaction in the glow stick is happening faster. The reaction happens faster, because increasing the temperature increases the rate of a chemical reaction.

"Compare and contrast the troposphere and the thermosphere:
I have one example already but I need some extra help, I would really appreciate it!
Answer: here it is :D
Explanation:As nouns the difference between thermosphere and troposphere. is that thermosphere is thermosphere (layer of the earth's atmosphere) while troposphere is troposphere. thermosphere. English. Noun. The layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere.
Answer:
thermosphere is thermosphere (layer of the earth's atmosphere) while troposphere is troposphere.
ation:
This layer also contains ratios of nitrogen and oxygen similar to the troposphere, except the concentrations are 1000 times less and there is little water vapor there, so the air is too thin for weather to occur. The thermosphere is the uppermost layer of the atmosphere.
In what type of soil would you recommend locating a drinking water well?
Options:
Sand
Gravel
Soil
Clay
Explain why.
Sand is best for the locating a drinking water well, it is free of rocks good for the water well, hence option A is correct.
What is sand?It is a dry, light, warm, and observe to be acidic and low in nutrients. Sandy soils are frequently suggested as light soils due to their high quantity of sand and little clay (clay measures more than sand).
There are four different types of soil:
Sandy soil.Clay Soil.Silt Soil.Loamy Soil.If soil comprises larger proportion of big particles, it is known as sandy soil. If the quantity of fine particles is comparatively higher, then it is named clayey soil. The quantity of large and fine particles is usually the same, then the soil is called loamy.
Therefore, sand is the best for the locating a drinking water well, hence option A is correct.
