Several plant and animal species present together at a place constitute a

Options

A. genus
B. population
C. biome
D. community

Explanation

To solve the question "Several plant and animal species present together at a place constitute a", we need to understand the terms related to ecology and the organization of living organisms. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Components
- The question mentions "several plant and animal species". Plants and animals are both living organisms that interact with each other in a specific area.

### Step 2: Define Key Terms
- In ecology, the term "population" refers to a group of individuals of the same species living in a particular area.
- A "community" consists of different populations of various species (both plants and animals) that live together and interact in a specific environment.

### Step 3: Identify the Correct Term
- Since the question specifies "several plant and animal species", we are looking for a term that encompasses multiple species.
- The term "community" is used to describe the assemblage of different species (both plants and animals) in a specific area that interact with one another.

### Step 4: Eliminate Incorrect Options
- The other options provided (genus, population, biome) do not accurately describe a group of multiple species:
- "Genus" is a taxonomic rank that groups species based on similarities.
- "Population" refers to individuals of the same species, not multiple species.
- "Biome" refers to a larger ecological area with similar climate and organisms, which is broader than a community.

### Step 5: Conclusion
- Therefore, the correct answer is that several plant and animal species present together at a place constitute a **community**.

### Final Answer
The correct answer is **community**.
