Gnom [1K]

Answer:

Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.

Explanation:

The saban hypothesis is believed to have originated in the saban, with the Austrolopitecus africanus being forced to affect this domain, which is why it acquired this adaptation mechanism.

The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.

In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.

The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.

Why do biologists measure the number of trophic levels in an ecosystem?

slega [8]

Answer:

Biologists measure the number of trophic levels in an ecosystem so as to check its stability and health.

Explanation:

Trophic levels are the feeding position in a food chain such as primary producers, consumers, etc. They are positions that an organisms occupies in a food chain (series of steps in which organisms transfer energy by eating or being eaten);- what it eats and what eats it.

Theoretically there is no any limit to the number of trophic levels in a food chain or number of organisms that live on each level.
