Science

3. Chemical substances that organisms need to grow, reproduce, and carry out other life processes.
5. Autotrophs that produce food using chemical energy (e.g., bacteria in deep-sea vents).
7. Organisms that cannot produce their own food and rely on other organisms for nutrition.
10. Autotrophs that produce food using light energy (e.g., plants, algae).
11. Consumer Herbivores that consume producers.
13. A consumer that eats both plants and animals (e.g., humans, bears).
14. A group of individuals of the same species living in the same area.
16. Autotrophs that generate food for an ecosystem (e.g., plants).
17. Heterotrophs that eat other organisms for energy.
18. A consumer that eats only plants (e.g., deer, rabbits).
21. A community of living organisms and their physical environment interacting as a system.

1. A consumer that eats only other animals (e.g., lions, sharks).
2. Organisms that break down dead or decaying matter (e.g., fungi, bacteria).
4. Non-living components of an ecosystem (e.g., sunlight, temperature, water, soil)
6. Living components of an ecosystem (e.g., plants, animals, bacteria).
8. Microscopic photosynthetic organisms found in aquatic environments, crucial for oxygen production.
9. Organisms that feed on dead organic matter (e.g., earthworms, vultures).
12. Organisms that produce their own food through processes like photosynthesis or chemosynthesis.
15. Cycling The movement and exchange of organic and inorganic matter back into the production of living matter (e.g., nitrogen, carbon cycles).
19. The total mass of all living organisms in a given area or ecosystem at a given time.
20. All the biotic (living) organisms in a particular area interacting with each other.
