Why are estuaries considered brackish?
- A.
Estuary waters are a mixture of tidewater and longshore current.
- B.
Estuary waters are a mixture of soundwater and ocean water.
- C.
Estuary waters are a mixture of soundwater and littoral drift.
- D.
Estuary waters are a mixture of fresh and salt water.
Correct Answer
D. Estuary waters are a mixture of fresh and salt water.Explanation
Estuaries are considered brackish because they are a mixture of fresh and salt water. This occurs when rivers or streams flow into the ocean, creating a transition zone where the two types of water mix. The fresh water from the rivers and streams is less dense and floats on top of the salt water, creating a brackish environment. This mixture of waters creates unique habitats that support a wide variety of plant and animal species adapted to tolerate the fluctuating salinity levels.Rate this question:

How is energy passed through the community? SCL pg. 10-13
- A.
Energy is passed through the community through feeding relationships.
- B.
Energy is passed through the community as organisms move about their habitat.
- C.
Energy is passed through the community through organism decomposition.
- D.
Energy is passed through the community as organisms breed and grow.
Correct Answer
A. Energy is passed through the community through feeding relationships.Explanation
Energy is passed through the community through feeding relationships. This means that organisms obtain energy by consuming other organisms in the community. This transfer of energy occurs as energy is transferred from one organism to another through the food chain. Producers, such as plants, convert sunlight into chemical energy through photosynthesis. Herbivores then consume these plants, transferring the energy to themselves. Carnivores then consume the herbivores, transferring the energy further up the food chain. This process continues, with energy being passed from one organism to another, ultimately sustaining the entire community.Rate this question:
