1. Which sequence represents the correct order of increasing complexity?

Which sequence represents the correct order of increasing complexity?

Population, ecosystem, biosphere, community

Community, biosphere, population, ecosystem

Population, community, ecosystem, biosphere

2. Classification of organisms reflects

Similarities.

Evolutionary history.

Neither Similarities Nor Evolutionary history.

Both Similarities and Evolutionary history.

3. An evolutionary tree

Shows common ancestors.

Depicts the history of a group of organisms.

Is based on appropriate data.

Shows how certain organisms are related.

All of these are correct.

4. An ecosystem, energy

Flows and nutrients cycle.

Cycles and nutrients flow.

And nutrients flow.

And nutrients cycle.

5. Which of these exhibits an increasingly more inclusive scheme of classification?

Kingdom, phylum, class, order

Phylum, class, order, family

Class, order, family, genus

Genus, family, order, class

6. An example of chemical cycling occurs when

Plants absorb solar energy and make their own food.

Energy flows through an ecosystem and becomes heat.

Hawks soar and nest in trees.

Death and decay make inorganic nutrients available to plants.

We eat food and use the nutrients to grow or repair tissues.

7. Energy is brought into ecosystems by which of the following?

Fungi and other decomposers

Cows and other organisms that graze on grass

Meat- eating animals

Organisms that photosynthesize, such as plants

All of these are correct

8. Organisms are related because they

All have the same structure and function.

Share the same characteristics.

Can all trace their ancestry to a common source.

All contain genes.

9. To remain homeostatic, organisms need to

Be multicellular.

Acquire material and energy from the environment.

Have a nervous system.

Respond to stimuli.

Both acquire material and energy from the environment and respond to stimuli.
