select the statement(s) that accurately describe the ecological relationships among organisms.
commensalism occurs when both organisms benefit from the relationship or interaction.
predators are organisms that get hunted and eaten.
mutualism occurs when one organism benefits and the other organism neither benefits nor is harmed by the relationship or interaction.
competition occurs when organisms challenge each other for resources.
parasitism occurs when one organism benefits and the other organism is harmed by the relationship or interaction.

Explanation:

• Commensalism is when one organism benefits and the other is neither helped nor harmed. So the first statement is wrong.
• Predators are the ones that hunt and eat. Prey are the organisms that get hunted and eaten. So the second statement is wrong.
• Mutualism is when both organisms benefit. So the third statement is wrong.
• Competition is indeed when organisms challenge each other for resources.
• Parasitism is when one organism benefits and the other is harmed.

Answer:

Competition occurs when organisms challenge each other for resources. Parasitism occurs when one organism benefits and the other organism is harmed by the relationship or interaction.
