Front

What is exponential growth?

Back

Exponential growth refers to a population increase that occurs when the growth rate is proportional to the current population size, leading to a rapid increase over time.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, illustrating how energy and nutrients flow through different trophic levels.

Front

What are producers in an ecosystem?

Back

Producers are organisms, typically plants and algae, that can make their own food through photosynthesis, forming the base of the food web.

Front

What does it mean for living things to grow and develop?

Back

Growth and development refer to the processes by which living organisms increase in size and undergo changes in their life stages, such as a caterpillar transforming into a butterfly.

Front

What is immigration in population dynamics?

Back

Immigration is the movement of individuals into a population from other areas, which can increase the population size.

Front

What is emigration in population dynamics?

Back

Emigration is the movement of individuals out of a population to other areas, which can decrease the population size.

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of a population within an ecosystem.

Front

What is a natural disaster?

Back

A natural disaster is a catastrophic event caused by natural processes of the Earth, such as earthquakes, floods, or hurricanes, which can significantly impact populations and ecosystems.

Front

What is competition in ecology?

Back

Competition occurs when individuals or species vie for the same resources, such as food, space, or mates, which can limit population growth.

Front

What is parasitism?

Back

Parasitism is a symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host), often harming it.
