Why do organisms change over time? How does the past help us predict the future? (think of the before/after cows)

Organisms change over time due to natural selection and genetic mutations.

Explanation:

An example of natural selection is the finches the scientist Charles Darwin studied in the Galapagos Islands. The finches had different shaped beaks which allowed them to adapt to different environments. An example of genetic mutation is if a person had an extra finger.The past helps us predict the future because if a change happened in the past to an organism, we can use the same change and apply it to other organisms which can help us determine what is to come in the future. Hope this Helped!!

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
