Determine the limiting factors that might exist in the example ecosystems below. 1.

A community of mussels, starfish, and algae exist in a small tide pool

2.

An oasis thrives around a small spring-fed pool in the middle of a desert

3. A population of elk is reproducing rapidly in a section of forest due to the absence of any predators

individual oxygen atoms are formed during photosynthesis.-c.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

c is the correct answer!
