Populations

Populations

By Hannah Homoelle

Poll

Would you rather get a penny and have it double every day for a month OR get $1000 per day for a month?

• Penny doubled

• $1000 per day

​This is how populations grow! They increase faster the bigger they are!!

Objective

I can predict the effect of limiting factors on populations.
I can interpret a population graph.

Always about 10X more PREY that PREDATORS because only 10% of energy moves between levels.

Multiple Choice

What is the term for all of the organisms of a species in an environment?

• population

• exponential growth

• carrying capacity

Open Ended

What is one example you can think of for a limiting factor?

Limiting Factors

Food, shelter, space, water, nutrients (oxygen, nitrogen), temperature, maters, pH, predators

​

Intraspecific competition - when members of the same species have to compete for resources​

Multiple Choice

How is the human population growing?

• logistic

• carrying capacity

• very little

• exponential

Multiple Choice

If a population is not being limited by external factors, what kind of growth is it undergoing?

• population ecology

• exponential growth

• logistic growth

• carrying capacity

Multiple Choice

What is the term for when a population is no longer growing because it has reached its set limit in the environment?

• exponential growth

• population dynamics

• food web

• carrying capacity

Open Ended

What is the carrying capacity for the population in this graph?

Multiple Choice

What happens to a population if it grows past its carrying capacity?

• all the organisms die

• some organisms die

• the population keeps growing

• more habitats are made
