Front

What environmental factor may contribute to an increase in a rabbit population?

Back

Decreases in predators.

Front

What does a decrease in predator population indicate about the bluegill population from 1995 to 1996?

Back

There was a decrease in predators from 1995 to 1996.

Front

What pattern was observed in wolf and moose populations from 1965 to 1970?

Back

A drop in wolf population and an increase in moose population.

Front

In a predator-prey relationship, what is the role of Species A if it is a predator of Species B?

Back

Species A is a predator and Species B is its prey.

Front

What does the interaction between a heron and a crocodile illustrate in terms of food webs?

Back

The heron eats baby crocodiles, and adult crocodiles eat herons.

Front

Define predator-prey relationship.

Back

A biological interaction where one organism (the predator) hunts and eats another organism (the prey).

Front

What is the significance of population dynamics in ecology?

Back

Population dynamics study the changes in population sizes and compositions over time, influenced by factors like predation, competition, and environmental changes.

Front

How can a decrease in predators affect the ecosystem?

Back

It can lead to an increase in prey populations, which may result in overgrazing or depletion of resources.

Front

What is the role of graphs in understanding population changes in ecology?

Back

Graphs visually represent data trends over time, helping to identify patterns in population dynamics.

Front

What is the impact of invasive species on native predator-prey relationships?

Back

Invasive species can disrupt existing predator-prey dynamics, often leading to declines in native species.
