What is a competitive relationship in an ecosystem?

Back

A competitive relationship occurs when two or more organisms compete for the same resources, such as food, space, or light. An example is two plants growing in the same space.

How does soil composition affect plant growth?

Back

Soil composition is crucial for plant growth; rich soil provides essential nutrients and support, leading to better plant health and growth.

Front

What are abiotic factors in an ecosystem?

Back

Abiotic factors are non-living components of an ecosystem, such as temperature, soil, water, and sunlight, that affect living organisms.

Front

How do organisms compete for abiotic factors?

Back

Organisms compete for abiotic factors by adapting to use available resources effectively, rather than fighting each other.

Front

What is cell theory?

Back

Cell theory is a fundamental scientific principle stating that all living organisms are made of cells, and cells are the basic unit of life.

Front

How does temperature range impact an ecosystem?

Back

Temperature range can significantly impact an ecosystem; extreme temperatures can limit the survival of certain species.

Front

What is an example of mutualism in an ecosystem?

Back

An example of mutualism is a bee pollinating a flower, where both the bee and the flower benefit from the interaction.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and supporting plant growth.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular ecosystem, including the number of different species and their interactions.

Front

How do invasive species affect ecosystems?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, leading to a decline in biodiversity.
