Explanation:

• First question: Population growth typically leads to an increased demand for resources (food, water, energy etc.). Economic gains stimulated by population growth is not always the case (depends on various factors like employment, infrastructure etc.). A small number of elderly citizens (assuming the graph shows that) would not lead to decreased demand for medical services as other age - groups also need medical care.
• Second question: A community is defined as potentially interacting populations of different kinds of organisms. One species in a specific environment is a population. Living organisms and their non - living environment is an ecosystem.
• Third question: When two organisms (owl and hawk) eat the same prey (mice), they are in competition for the same food resource. Predation is when one organism eats another (e.g., cat eating mouse). Mutualism is a beneficial relationship for both (e.g., bee and flower).
• Fourth question: When two different populations in a community benefit from their relationship with each other, it is called mutualism. There is no such term as “benefitism” in ecological relationships. Competition is when they compete for resources.

Answer:

• First question: an increased demand for resources based on population growth
• Second question: potentially interacting populations of different kinds of organisms
• Third question: competition
• Fourth question: mutualism
