What happens when a population has abundant resources?
Populations with unlimited resources grow exponentially—with an accelerating growth rate. When resources become limiting, populations follow a logistic growth curve in which population size will level off at the carrying capacity.
How does population affect our natural resources?
Explanation: Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. Scientific and technological innovations mean that we are improving our efficiency at using and harvesting natural resources.
What is the relationship between population resources and environment?
The magnitude of the threat to the ecosystem is linked to human population size and resource use per person. Resource use, waste production and environmental degradation are accelerated by population growth.
How does population size relate to resource availability in an environment?
Answer: The correct answer would be “population size is limited by the availability of resources”. Limiting factors in an ecosystem such as the availability of resources or food limit the growth rate of a population in any ecosystem. The population size can not reach beyond the carrying capacity of the ecosystem.
What happens if the population of an ecosystem is too big?
If a population grows too large, the ecosystem could collapse. Populations go through cycles of growth and contraction. If a population grows too big too fast then the lack of resources usually results in a population crash.
How are wildlife populations dependent on the environment?
Wildlife populations depend on their environment or habitat to receive the basic needs for survival. An ecosystem or habitat provides populations of wildlife with food, water, shelter and space. If all four of these basic needs are not available in a suitable arrangement, populations of wildlife can not exist.
How does an ecosystem affect the number of animals?
Insect populations could increase because of fewer insect eating birds and trees and other plants could be negatively affected. The whole ecosystem is affected. The amount of suitable habitat for a species of wildlife will determine the number of animals that can survive in the area.
How does a population form a community in an ecosystem?
Populations in ecosystems: Populations of different species form a community within a habitat. The community together with non-living features (known as abiotic conditions) which include temperature and water form a community.
