- B.
It is not bad.
- C.
It blocks sunlight from reaching SAV's.
- D.
None of the above.
Correct Answer
C. It blocks sunlight from reaching SAV's.Explanation
Algae blooms are bad for the water because they block sunlight from reaching submerged aquatic vegetation (SAV's). Sunlight is essential for photosynthesis, which is the process that SAV's use to produce oxygen and provide habitat for aquatic organisms. When algae blooms cover the surface of the water, they prevent sunlight from penetrating the water column, leading to a decrease in oxygen levels and disrupting the ecosystem. This can result in the death of SAV's and other aquatic organisms, leading to a decline in water quality and biodiversity.Rate this question:

- D.
Food Chain
Correct Answer
D. Food ChainExplanation
Food energy is passed through different organisms through a food chain. A food chain is a linear sequence in which each organism is eaten by the next organism in line. It starts with a producer, such as plants, which convert sunlight into food energy through photosynthesis. The primary consumers, such as herbivores, eat the producers, and then the energy is transferred to the secondary consumers, such as carnivores, who eat the primary consumers. This transfer of energy continues through the chain, with each organism being a source of energy for the next organism.Rate this question:

What is a first level consumer?
- A.
A consumer that eats producers.
- B.
A consumer that eats animals.
- C.
A synonym for carnivore.
- D.
None of the above
Correct Answer
A. A consumer that eats producers.Explanation
A first level consumer is a type of organism that directly feeds on producers, which are plants or other autotrophic organisms that produce their own food through photosynthesis. This means that the first level consumer obtains its energy and nutrients by consuming plants or algae. This is different from a consumer that eats animals, which would be a second or higher level consumer. The term "synonym for carnivore" is not accurate as carnivores can be consumers at any trophic level, not just the first level.Rate this question:

The oysters' niche in the Chesapeake Bay is to clean the bay. Oysters are filter feeders, meaning they extract nutrients and particles from the water as they feed. This process helps to improve water quality by removing excess nutrients and sediment. Oysters play a crucial role in maintaining the health and balance of the ecosystem by filtering the water and reducing pollution levels. They are considered natural water purifiers and their presence is essential for the overall cleanliness and well-being of the Chesapeake Bay.Rate this question:
