NTI - Day 2

Front

What do J and S curve models assume about population growth?

Back

Both J and S curve models assume that population growth is proportional to population size.

Front

What is the carrying capacity of the human population?

Back

The carrying capacity could be as high as 11 billion or more, could be a number we have already surpassed, or the number is not known.

Front

Would all the deer and mice living in a forest be considered a population?

Back

No, a population consists of individuals of the same species.

Front

What occurs when population growth slows and population size levels off?

Back

Logistic growth occurs when population growth slows and population size levels off.

Front

What happens to the population if the death rate is larger than the birth rate?

Back

The population size will decrease.

Front

Define carrying capacity.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can support sustainably.

Front

What is exponential growth in population dynamics?

Back

Exponential growth is when a population increases rapidly due to abundant resources, leading to a J-shaped curve.

Front

What factors can limit population growth?

Back

Factors that can limit population growth include food availability, predation, disease, and habitat space.

Front

What is the difference between density-dependent and density-independent factors?

Back

Density-dependent factors are influenced by population density (e.g., competition, disease), while density-independent factors affect populations regardless of density (e.g., natural disasters).

Front

What is a population?

Back

A population is a group of individuals of the same species living in a specific area.
