Aquatic Science Unit 5 Pre Test

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread rapidly in a new environment, often outcompeting native species for resources.

Front

Why do invasive species grow quickly in new environments?

Back

Invasive species have no natural predators in their new environment, allowing their populations to grow unchecked.

Front

What is the impact of copper compounds on aquatic plants?

Back

Copper compounds interfere with photosynthesis, leading to a reduction in plant populations when spilled in aquatic environments.

Front

What are abiotic limiting factors in an ecosystem?

Back

Abiotic limiting factors are non-living components that affect the growth and survival of organisms, such as water, space, and oxygen.

Front

What role do plants play in the carbon cycle?

Back

Plants take in carbon dioxide from the atmosphere during photosynthesis, which is then used to produce energy and oxygen.

Front

What happens when a population exceeds its carrying capacity?

Back

When a population exceeds its carrying capacity, it leads to resource depletion, resulting in a decline in population size.

Front

Define carrying capacity.

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What are the consequences of reduced plant populations in aquatic ecosystems?

Back

Reduced plant populations can lead to decreased oxygen levels, loss of habitat for aquatic organisms, and increased water temperature.

Front

How do invasive species affect native ecosystems?

Back

Invasive species can disrupt food webs, outcompete native species for resources, and alter habitat structures.
