Answer:

Sun > Grass > Deer > Lion

Explanation:

The sun begins a food chain because its light is needed for a plant, in this case grass, to grow.

An animal that eats grass is the deer, who is a primary consumer.

An animal that eats deer is the lion, who is a tertiary consumer in this case.

The lion has no natural predator, and thus is at the top of this food chain.

This ecosystem can be one found where grass, deer and lions exist, for example, the deciduous forest in the eastern United States.

Oksanka [162]

Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.

<h3>What are the effects of irrigation agriculture on river basins?</h3>

Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.

Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.

One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

katrin [286]

A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The point of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. It occurs in freshwater protists, but mainly in the kingdom Protista as a whole.
