What types of fossils would provide the best evidence that the Earth’s continents used to be connected? Birds, fish or land animals? Explain why.

Land animals.

Explanation:

Birds and fish could move between continents that were not connected. If fossils of the same land species are found on what is now different continents, that implies that the land masses were once connected and that animal was able to travel between them.

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
