Which of the following factors often determine the type of benthic animals that thrive in aquatic environment?

Options

A. Type of plants
B. pH of water
C. Sediment characteristics
D. Light availability

Answer

To determine the type of benthic animals that thrive in an aquatic environment, we need to consider several factors, particularly focusing on sediment characteristics. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Benthic Animals**:
- Benthic animals are organisms that live on or in the bottom sediments of aquatic environments. They can include a variety of species such as worms, crustaceans, and mollusks.

2. **Identifying Key Factors**:
- The type of benthic animals present in an environment is influenced by various factors, but sediment characteristics play a crucial role.

3. **Sediment Characteristics**:
- Sediments are composed of solid particles that can be organic (derived from living organisms) or inorganic (derived from non-living sources).
- The composition, size, and texture of these sediments can affect the types of organisms that can inhabit the area.

4. **Sediment Movement**:
- Sediments can move through water currents, which can transport different types of sediments to various locations, thereby influencing the benthic community.

5. **Conclusion**:
- Therefore, the correct answer to the question is that sediment characteristics are a determining factor for the types of benthic animals that thrive in aquatic environments.

### Final Answer:
The type of benthic animals that thrive in an aquatic environment is often determined by sediment characteristics.
