When populations be crowded what do organisms compete with?
food and space
What best describes the impact of the farming revolution?
steady food supplies meant healthy growing populations
What most likely happened to the herbivores and smaller carnivores in those local food chains after the predators disappeared?
Their populations increased.
What most likely happened to the herbivores and smaller carnivores in those local food chains immediately after the predators disappeared?
their populations increased
What if the Arctic fox population increased?
If the population increased, there would be a decrease in the populations of prey items, such as lemmings and hares. If the prey items decreased too much the Arctic fox populations would also decrease with the limited food available.
What is the Malthus Theorem?
Malthusian theorem is a population projection that suggests the population will exceed the available food supply because populations grow at geometric rates, while food supplies grow at arithmetic rates
Are wildlife populations static (stay the same) or do they fluctuate (change) as part of an overall balance?
They change over time in response to factors in the environment such as weather and food supplies.
How many woman are in Pennsylvania?
enough to cause devastation of food supplies, thus causing the population to collapse.

What did Thomas Robert Maithus claim?
Malthus claimed that while food supplies grow exponentially, populations can grow geometrically.It basically means that starvation is a normal ecological process.
How does Rapid population growth upset the balance of nature?
The increase of population of one species can result in less food for competing species, and more food for predators. Larger populations can cause several problems: more rapid exhaustion of available resources (food, space), faster spread of disease, and extinction of less populous (or less adaptive) competing species. Examples : Hordes of locusts can consume the food supplies of animals and humans. Too many sheep can denude pasture land. Large scavenger populations could reduce the food supply available to endangered bear species.
Upstream?
involve policy approaches that can affect large populations through regulation, increased access, or economic incentives. Policy to have nutritional information included on food packaging is an example
