Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What happens to sugar production if carbon dioxide is removed from a plant's environment?

Back

Sugars will not be produced.

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 the environment.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably without degrading the habitat.

Front

What occurs if a predator is removed from an ecosystem?

Back

If a predator is removed, the population of its prey may increase, potentially leading to overgrazing or depletion of resources.

Front

What is exponential growth?

Back

Exponential growth is a rapid increase in population size when resources are unlimited, characterized by a J-shaped curve on a graph.

Front

What is logistic growth?

Back

Logistic growth is a population growth model that shows how a population grows rapidly at first and then levels off as it reaches carrying capacity, forming an S-shaped curve.

Front

What role do sea otters play in their ecosystem?

Back

Sea otters are a keystone species that help maintain the balance of marine ecosystems by preying on sea urchins, which in turn helps protect kelp forests.

Front

What is the impact of an increase in the sea urchin population?

Back

An increase in the sea urchin population can lead to overgrazing of kelp forests, resulting in habitat loss for many marine species.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients from producers to various levels of consumers.
