Ecology

2. - an animal that is hunted, caught, and eaten by another animal, which is called a predator
3. -a natural, inborn urge to act a certain way without thinking or learning it first
5. - an animal that hunts, kills, and eats other animals for energy and nutrients
6. - the natural movement of water molecules across a semipermeable membrane from a region of higher water concentration to a region of lower water concentration
7. - when energy is passed in an ecosystem from one trophic level to the next, only about 10% of that energy is stored as flesh and passed on
8. - an external environment with a higher solute concentration compared to a cell's cytoplasm, causing water to leave the cell via osmosis
12. - he total quantity or weight of organisms in a given area or volume
13. - an environment with the same solute concentration as a cell's cytoplasm, resulting in equal water potential
14. - organisms that break down dead plants, animals, and waste into simpler nutrients
16. - community of living organisms interacting with each other and their non-living environment in a specific area
17. - an organism that cannot produce its own food and must eat other organisms to gain energy, acting as a heterotroph
18. - the natural home or environment of an animal, plant, or other organism.
19. - a diagram showing how multiple food chains in an ecosystem are interconnected, illustrating who eats whom

1. -the process by which plants, algae, and some bacteria use sunlight, water, and carbon dioxide to create their own food and release oxygen
4. - the continuous process by which nitrogen moves between the atmosphere, soil, water, and living organisms, transforming into various chemical forms
9. - a person, company, or country that makes, grows, or supplies goods or commodities for sale
10. - a simple monosaccharide sugar and the primary, most accessible energy source for living cells, often termed "blood sugar"
11. -has a lower solute concentration outside the cell compared to inside the cell
14. - the passive, net movement of particles from a region of higher concentration to a region of lower concentration
15. - the thin, flexible, oily boundary surrounding all living cells that separates the cell’s interior from the outside environment
