The competition of individuals may be for food , space , light and other physical factors .

Answer

**Step-by-Step Solution:**

1. **Understanding Competition in Ecosystems**:
- Competition occurs when individuals or species compete for limited resources. This can include food, space, light, and other physical factors necessary for survival and reproduction.

2. **Competition for Food**:
- Consider a scenario with two predators (A and B) competing for the same prey (Prey 1). If both predators are hunting the same prey, they will compete against each other for this food resource. This illustrates that competition for food is a common occurrence in ecosystems.

3. **Competition for Space**:
- Imagine two species (Species A and Species B) that inhabit a limited area. If both species require the same space to live and reproduce, they will compete for that space. This shows that competition for space is also a valid form of competition in ecosystems.

4. **Competition for Light**:
- In a tropical rainforest, there are both large and small trees. The large trees create a canopy that blocks sunlight from reaching the smaller trees. As a result, the smaller trees struggle to receive adequate light for photosynthesis, leading to competition for light among the plants. This example highlights the competition for light in densely populated ecosystems.

5. **Conclusion**:
- Given the examples of competition for food, space, and light, we can conclude that the statement is true. Individuals do compete for these essential resources in their ecosystems.

**Final Answer**: True
