True or false? Competition between two different species might affect their rates of population growth.

Answer: True

Competition between two different species can significantly affect their rates of population growth. This phenomenon is well-documented in ecology and is often referred to as interspecific competition. When two species compete for the same limited resources, such as food, space, or mates, it can lead to a decrease in the population growth rates of one or both species.

The effects of competition can manifest in various ways. For instance, if one species is more efficient at resource utilization, it may dominate the resource pool, thereby limiting the growth opportunities for the other species. This competition can also lead to changes in reproductive rates, survival rates, and overall population dynamics.

Furthermore, in some cases, resource competition can drive adaptations in either or both species, leading to niche differentiation or resource partitioning, which can mitigate the competitive effects over time. Overall, the interaction between species through competition is a key factor influencing population growth rates in ecological communities.
