Final answer:
In competition between plants, they compete for water, space, and light when these resources are limited, with the plant that can better acquire these resources typically coming out on top. option c is correct.
Step-by-step explanation:
The question asks which statement about competition between plants is true. The correct answer is c. Plants compete for water, space, and light when they are limited. Competition is a relationship between organisms that strive for the same resources in the same place at the same time, and this includes plants.
For instance, if two plants are growing close together, they will compete for sunlight, with the taller plant generally getting more light and therefore being more likely to thrive. Additionally, they may compete for soil nutrients and water, with the plant that can more effectively take up these resources usually having a competitive advantage. These interactions illustrate intraspecific competition, where members of the same species compete for resources.
Competition among plants is a common phenomenon in ecosystems where resources are limited. Plants may compete for essential resources like water, space, and light, which are crucial for their growth and survival. The competition for resources influences plant growth, distribution, and the overall structure of plant communities in various ecosystems. Therefore, option c is the most accurate statement reflecting the reality of plant competition in natural environments.
