2.-EVALUATION.
2.1 What is ecology?
1. - All life on Earth exists in:
The biosphere
2. - What term describes a group of different species living together in a defined area?
A community.3. - Name the different levels of organization within the biosphere, from smallest to largest.
1. species,
2. population,
3. community,
4. ecosystem,
5. biome,
6.biosphere.
4. - How do ecologists use modeling?
They use mathematical formulas based on data gathered through observation and experimentation.
5. - Give an example of how a biotic factor could affectthe organisms in an ecosystem.
For example the water covering the edges of wetlands and soil nutrient supply.
CRITICAL THINKING.
6. - Designing an experiment.
7. - Ask. You live near a pondyou've seen for years. A year notes that water is stagnant with excessive growth of green algae. What are some of the questions you might ask about this unusual growth?
2.2 Energy producers andconsumers.
8. - Primary producers are organisms that:
They use the energy taken from the environment to convert inorganic molecules into complex organic molecules.
9. - Which of the followingorganisms is a decomposer?
Microbes.
10. - Which of the following describes how to obtain their energy all consumers?
By eating organisms that are alive or once were alive.
11. - What ischemosynthesis?
Process using autotrophic organisms use the energy stored in chemical bonds to produce rich carbohydrates into energy.
CRITICAL THINKING.
12. - Sort. Classify each of the following as aherbivore, a carnivore, an omnivore or a detritivore: Earthworm, bear, cow snail, owl and human.
13. - Propose a hypothesis. People who explore caves where there is running water but no sunlight arefrequently populated with unique types of species and insects. What can propose hypotheses to explain last energy source for these organisms?
2.3 Flow of energy in ecosystems.
