What’s the answer?

1. Periods of stasis, during which organisms do not change in the fossil record, can be
accounted for in modern evolutionary theory by understanding that -
A. the adaptation of plants and animals have not changed very much in the fossil record.
B. the fossil record has gaps caused by slower than usual rates of sedimentation.
C. a constant climate gives an advantage to species that stay in one place.
D. some organisms live for long periods in a habitat with no selective pressure.

What would happen to the nutrients in an ecosystem if decomposers, such as bacteria, didn’t exist there?

Indicate whether the following statements about the biases in the fossil record are true or false. a) inland species are more likely to be preserved than marine species b) organisms with hard body parts are more likely to be preserved than are those composed soft tissues. c) species that existed over a larger area are more likely to be preserved than species existing over a smaller area. d) organisms that lived very long ago are more likely to be found as fossils than organisms that lived relatively recently e) the fossils of larger organisms are more likely to be found than the fossils of smaller organisms
