What is mutualism

Interaction between two or more species, fish.

What shaped curve will a graph showing exponential growth be

J -shaped curve.

What are the 2 possible outcomes of competition that we discussed

Looser could be kicked out of habitat, dividing the resources.

What is an example of density-independent population regulation

Natural disasters like forest fires.

What is parasitism

One organism lives in or on another organism, a worm.

What does abiotic mean

Physical other than biological.

What is density-dependent population regulation

Population growth rates are regulated by density.

What does biotic mean

Relating to living things.

What shaped curve with a graph showing logistic growth be

S-shaped curve.

What is biodiversity

A biological variety and variable of life.

What is a population

A group of individual organisms that live together.

What is a niche

A match of species to a specific environmental condition.

What is predation

A predator and Prey, Fox and Rabbit.

Why is a fundamental niche different from a realized niche

A realized niche is an actual environment where the species lives.

What is a community

A social unit.

What is a keystone species

A species an ecosystem heavily depends on.

What is commensalism

What is density-independent population regulation

Any force that affects a population.

What are two things that will cause a population's growth to INCREASE

Birth rates, and the amount of food.

How can predation help increase biodiversity

By preying and competitive dominants.

What is an example of density-dependent population regulation

Competition for food.

What is logistic population growth

Competition increases and resources become scarce.

What is herbivory

Consumption of plant materials, like Deer.

What are two things that will cause a population's growth to DECREASE

Death rates, and the amount of food.

Under what conditions does exponential growth typically happen

Few individual growths and plentiful resources.

What factors determine the carrying capacity of a habitat

Food and water availability.

How can predation affect competition

High predation can make a species sensitive to even a small amount of competition.

What is exponential population growth

The growth rate stays the same regardless of population growth.

What is carrying capacity

The number of people or living organisms without environmental degradation.

What is coevolution
