• deserts.

• tropical rainforests.

• temperate grasslands.

Resources such as water, food, or sunlight are likely to be limiting factors

• when a population is approaching the carrying capacity.

• when population size is decreasing.

• when predators eat their prey.

• when the population is small.

Which habitat exhibits the greatest biodiversity?

• A habitat with 15 different species with about 300 individuals each
• A habitat with 10 different species with about 75 individuals each
• A habitat with 4 different species with about 150 individuals each
• A habitat with only one species with about 2000 individual

Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
• Because it’s better to have only one variation of each species.
• Because it better to only have a few species on Earth.
• Honestly, I have no idea what biodiversity is!

What statement is TRUE about the graph?

• The prey is the green line because there needs to be more prey than predators.
• The prey is the red line because there needs to be more predators than prey.
• The green line is the producers
• The red line is the producers
