A children's section at a zoo has 10 goats. How could a scientist demonstrate competition between the goats in this area?
When there is no competition for resources and population density is low
Quantity of light and nutrients
A third population should be introduced.
The niche requirements of each species
The population size of both species is the same.
When there is a high population density
Competition can limit or deplete biotic and abiotic resources.
The scientist could give the goats a limited amount of food every day.
In a forest, two trees are growing next to each other. One tree is growing strong and tall. The other tree appears weak and small. Which of the following describes two natural resources that both trees compete for in this area?
When there is no competition for resources and population density is low
Quantity of light and nutrients
A third population should be introduced.
The niche requirements of each species
The population size of both species is the same.
When there is a high population density
Competition can limit or deplete biotic and abiotic resources.
The scientist could give the goats a limited amount of food every day.
Different species compete for resources in a given area when:
When there is no competition for resources and population density is low
Quantity of light and nutrients
