why does most communities have only about three or four trophic levels

Answers

Answer 1

Answer:

read below

Explanation:

As you progress through each trophic, each organism on that level loses energy gained from the previous trophic. This is due to losing energy through wasted material (e.g. bones) and to life processes, 7 of which can be remembered by MRS GREN:

M ovement

R espiration

S ensitivity

G rowth

R eproduction

E xcretion

N utrition

This means that each time, energy is wasted and lost from the food chain. More than four trophics would result in so much energy being lost from the initial trophic (producer), that it would be largely pointless!

The layer of greenhouse gases is permeable to one side and not permeable to another side.

Explanation:

Greenhouse gases such as carbondioxide, methane and water vapors etc formed a layer which allow the sun radiation to the earth surface but when these radiation reflected back, this layer traps these reflected radiation and the radiation remain suspended in air which heat up the particles present in the air and increases the temperature which causes global warming of earth surface. This phenomenon is also called greenhouse effect and it is also very useful in growing crops in cool seasons. So this layer is permeable from one side and not permeable from another side.

To study “the world in spatial terms” means to study __________.
A.
human systems
B.
environments
C.
locations
D.
regions

Answers

Answer:

the answer is c

Explanation:

To study "the world in spatial terms" means to study locations. The correct option is c.

In spatial terms, the world encompasses the placement of items in the world. While geography is more than just maps, it does take into account the location of places and how it affects the issue.

Absolute and relative location are notions in geography. Absolute location is one that does not alter, such as your longitude and latitude, whereas relative location is one that is relative to another, such as living between the Catholic church and the grocery.

Therefore it can be said that to study "the world in spatial terms" means to study locations.

Thus, the correct option is c.

These all activities have a negative effect on the whole environment including the rainforest. Some of the negative effects of such activities on rainforest are as follows:

Deforestation leads to a decrease in forest numbers and inrease global warming which lead to climate change and reduces amount of rain in rainforests. Hunting or poaching results into imbalancing the food chain in the environment which affect the wildlife population in the rainforests.There are many minerals extracted from rainforests such as gold, copper, and diamonds, which distruct the rainforests ecosystem and its wildlife.Industrial construction or roads construction across rainforests leads to deforestation and increases pollution in rainforest ecosystem.

Which factor determines, or which factors determine, the density of ocean water? temperature salinity temperature, salinity, and light penetration temperature and salinity

Answers

Answer

Temperature and Salinity

Explanation:

The two key factors that determine the density of ocean water are the temperature of the water as well as the salinity of the water.

Theoretically the density of ocean water at the sea surface is usually about 1027 kg/m3. When the temperature is low then the density of ocean water increases until freezing of the water occurs.When there is also increase in Salinity if water the density of water also increases. However the temperature of an ocean have more impact on the density than the salinity of the ocean.

Density of ocean is usually calculated through the situ measurements of temperature, salinity by taking the sample of the ocean and taking it to laboratory

Occasionally earthquakes occur as a result of collisions along oceanic-continental convergent boundaries. Where do these earthquakes most likely occur?

on land but close to oceans
inland, far from the coast
in the middle of the oceans
anywhere there are mountains

Answers

Answer:

 on land but close to oceans

Explanation:

A boundary between an oceanic plate and a continental plate will be near a coastline., not "far from the coast" or "in the middle of oceans."

Often, mountains are also near that boundary, but mountains may also exist elsewhere, so "anywhere there are mountains" is not an apt description.

The best choice is "on land but close to oceans."
