What is divergent evolution, convergent evolution, and co-evolution?

Convergent evolution shows how species have evolved separately but have similar (analogous) structures. Divergent evolution demonstrates how species can have common (homologous) anatomical structures which have evolved for different purposes.

Explanation: no explanation but thats what it means

Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. The activity of each species that participates in the interaction applies selection pressure on the others.

Explanation:

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
