Which of the following statements is correct for species

Options

A. The members of a species occupy the same habitat
B. They are morphologically similar
C. They can interbreed among themselves
D. They cannot interbreed with members of the other species

Explanation

To determine which statement is correct for species, let's analyze the provided options step by step:

### Step 1: Understand the Definition of Species
- A species is defined as a group of organisms that can interbreed and produce fertile offspring. This concept is known as the biological species concept, which was proposed by Ernst Mayr.

### Step 2: Analyze Each Statement
1. **Members of species occupy the same habitat.**
- While members of a species often share a habitat, this is not a strict requirement. Different species can occupy the same habitat without interbreeding.

2. **They are morphologically similar.**
- Members of a species tend to have similar physical characteristics (morphology), but this is not always the case. There can be variations within a species.

3. **They can interbreed among themselves.**
- This statement aligns with the biological species concept. Members of a species can interbreed and produce fertile offspring.

4. **They cannot interbreed with members of other species.**
- This statement is also true according to the biological species concept, as species are reproductively isolated from one another.

### Step 3: Identify the Correct Statements
- The correct statements regarding species are:
- They can interbreed among themselves.
- They cannot interbreed with members of other species.

### Conclusion
The most accurate and comprehensive statement regarding species is that they can interbreed among themselves and cannot interbreed with members of other species.

### Final Answer
The correct statements for species are:
- They can interbreed among themselves.
- They cannot interbreed with members of other species.
