What is population size?

Back

Population size refers to the number of individuals in a specific species within a defined area at a given time.

How does an increase in phytoplankton affect the food web?

Back

An increase in phytoplankton provides more food for herbivores like shrimp, which can lead to an increase in their population.

Front

What is the role of sunlight, water, and minerals in plant growth?

Back

These factors are essential for photosynthesis and nutrient absorption, limiting the number of plants that can thrive in an ecosystem.

Front

What happens to the impala population if the cheetah population decreases?

Back

The impala population is likely to increase due to reduced predation.

Front

How does drought affect the black bear population?

Back

A drought can lead to a decrease in food availability, causing the black bear population to decline.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms where each is eaten by the next in the chain, illustrating feeding relationships.

Front

What is a predator?

Back

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

Front

What is the impact of introducing a new predator to control a population?

Back

Introducing a new predator can help reduce the population of prey species, which can lead to changes in the ecosystem.

Front

What is carrying capacity?

Back

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

Front

What is the relationship between food availability and population size?

Back

Food availability directly affects population size; less food leads to smaller populations.
