2. Explain your answer
1. The arrow would be pointing from the prairie dog to the coyote.
2. The arrow points into the direction of energy flow.
How do predators improve the genetic makeup of prey populations?
- Improve the genetic make up of a prey population by catching the weak and the diseased.
How are deciduous forests able to conserve water?
This Boxer Crab carries a pair of stinging anemones in its claws, which it uses to defend itself from predators. The anemones get to move around which increases their food supply.
What type of symbiosis is this? What Marine biome zone would this be a part of?
This is an example of mutualism.
Boxer crabs and anemones are a part of the Neritic Zone.
The open water zone is also known as the ____________ zone
Photic zone

1. algae bloom
2. Blocks sunlight to the water, Oxygen content decreases

grass, or weeds
The amount of trophic levels within an ecosystem are limited because
1. Loss of energy from one trophic level to the next
The ants lay eggs on acacia tree so they get a nice safe place for their eggs. The acacia covers the infected area with brown flesh (called a gall.) The plant has to use valuable resources to create the gall. What type of symbiotic relationship is this?
