Mr. Langdon left a brush pile when harvesting his woodlot. Why is it a good
management practice for improving wildlife?
1. Cuts down on the number of mosquitoes
2. Gives wildlife easy access to food
3. Keeps water from becoming contaminated

Carrying capacity refers to:

When a farmer leaves crop residue standing, the MOST likely result is:

2. An increase in wildlife population due to increased food supply.
3. Increased competition from wildlife for the food supply.
4. Sick wildlife that are poisoned by pesticides.
Managed hunting is a term that refers to:
1. The number of animals competing for the food supply.
2. Removing some game that would otherwise be lost due to natural causes.
3. Being responsible for endangering some wildlife species.
4. The loss of animals due to natural predators.
A DECREASE in habitat quality if often the result when:
1. Carrying capacity is more than the number of wildlife living in the habitat.
2. More than one type of wildlife live in a habitat.
3. Population of wildlife in habitat is more than the carrying capacity.
4. The habitat is too large for the number of wildlife.

as a result of malnutrrition?
