How can changes in trophic levels affect an ecosystem’s health and stability?

Biology
1 answer:
arsen [322]3 years ago
4 0

Answer:

Changes in the basal levels that are on the bottom of the food chain.

Explanation:

Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.

Answer:

The correct answer is - NO.

A pulley system has an mechanical advantage of 10. If a mover used this pulley to lift a piano with a force of 1500 N a distance
Jlenok [28]
Answer:
(a) 145 N
(B) 40 N
(c) 10 ropes
Explanation:
Mechanical advantage, where and are input and output force respectively
Since MA is given as 10 and input force is 1450 N

Therefore, the mover must use a force of 145 N
(b)
Since also and the is given as 4 m then

(c)
Literally, we need 10 rope segments to support the piano since we utilize the mechanical advantage
