Unit 3: Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is carrying capacity?

Back

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

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new environment, can cause harm to the ecosystem, economy, or human health.

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is exponential growth?

Back

Exponential growth occurs when the growth rate of a population is proportional to its current size, leading to rapid increases under ideal conditions.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first and then slows as it approaches the carrying capacity.

Front

What is competition in an ecosystem?

Back

Competition occurs when two or more organisms vie for the same resources (like food, space, or mates) in an ecosystem.

Front

What happens during a population die-off?

Back

A population die-off occurs when the number of individuals in a population decreases significantly, often due to resource depletion or environmental changes.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow.

Front

What is the difference between a predator and prey?

Back

A predator is an organism that hunts and eats other organisms (prey) for food.
