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!

O Back-and-forth movement loosens sediment and rock.
O Large rocks are picked up and deposited in new areas.
O Continuous impacts build up sediment and rock.
O Loose sediment is picked up and blown to other locations.​

Answers

Answer:

A.) back-and-forth movement loosens sediment and rock

Explanation:

I got it right on my test

The back and forth movement erode the coastline

Let understand that "Coastline" is the area where the land meets the ocean. In some places, a coastline serves as beaches for entertainment.

Ocean waves keeps moving back and forth the coastline leading ro gradual erosion of the coastline particles into the ocean

Also, the Destructive waves have stronger back-washes and thus contribute to larger eroding agent for coastline because the force of the water removes the top layer with force.

In conclusion, the back and forth movement of the water continually loosens the sediment on the coastline till they get smoother and then eroded into the water.

What is dredging and why is it necessary? (2)

Answers

Answer:

Dredging is a process used to remove accumulated sediment from the bottom, and in some cases, the banks or sides of a river, lake, stream or other body of water. A specialized piece of equipment called a dredge creates a vacuum that sucks up and pumps out the unwanted sediment and debris.

Explanation:

Answer:

Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.

What factors affect the processes operating along a stretch of coastline?

Answers

The rock type/geology

The angle of the slope

Weather conditions

The amount of vegetation

The amount of human interference

The key factors which affect coastlines are:

The rock type/geology  The fetch of the wave and the strength of the wind.  The angle of the slope – steep slopes erode more violently and frequently. Weather conditions – freezing temperatures and heavy rain increase weathering and the rate of erosion.

Despite promising signs that lack of human activity during times of lockdown had led to flourishing wildlife across the world, loss of income is causing some people to exploit the environment. Evaluate this statement.

Answers

Answer:

The statement is true, and represents a situation that has happened many times before.

Explanation:

First of all, the lockdown has only been strict, and for brief periods of time, in mostly developed countries. In the majority of developing countries, the lockdown has been more flexible, because a big part of the population cannot stay inside for more than a few days, since they have to leave their homes to work and make a living.

The fall in economic activity leads some people to overexploit the enviroment in order to compensate. For example, poor farmers may burn more forest to increase crop sizes, and fishermen may overfish in some areas.
