A pond’s water level drops for weeks. Predict what happens to the fish population and name the limiting factor.
Fish decrease; limiting factor = water (or oxygen)

Tick on a dog—one benefits, one is harmed. Name the interaction and the roles.
What is parasitism? (tick = parasite, dog = host)

In an energy pyramid:
- which level has the most energy?
- why do higher levels usually have less energy?
Producers (the bottom of the pyramid) have the most energy.
Higher levels have less energy because they do not get their energy from a direct source (like the sun). Consumers have to get their energy from other organisms.

B) “Ducks, fish, insects, and plants in City Park Pond” → ________
C) “City Park Pond + water, rocks, air, and sunlight” → ________
D) “Desert areas around the world” → ________
A) Population B) Community C) Ecosystem D) Biome

What are the three statements of the cell theory?
What are
1. All living things are made of cells.
2. All cells come from pre-existing cells.
3. Cells are the basic unit of life.

In a meadow food web:
grass → rabbit → hawk AND
grass → grasshopper → frog → hawk
If the hawk population drops, what is one population likely to increase and one likely to decrease? Explain briefly using the food web.
Increase: rabbits or frogs/grasshoppers (fewer predators).
Decrease: grass (more rabbits/grasshoppers eating it).

Order these (small→big): biosphere, ecosystem, organisms/species, community, biome, population.
What is organisms/species → population → community→ ecosystem→ biome→ biosphere?
