Select the words that will correctly complete the passage. The fossil record provides evidence about
prehistoric organisms and ecosystems

. Scientists have fossil specimens that
show that nearly every species that evolved is extinct today

. Of the quarter-million or so species found in the fossil record, the majority are
larger than

living species today. One of the drawbacks of fossils is that we cannot directly observe the organisms. This limitation means that scientists
must usually infer how organisms behaved

.

Texas bluebonnet plants seen in this photo are an example of which ecological unit?

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.

Name one similarity and one difference between the morphology of a brachiopod and a bivalve
