19 Questions
Match the ecosystem interaction with its description:
Predation = One species consumes another for benefit Mutualism = Symbiotic relationship where both species benefit Competition = Occurs when species compete for limited resources Parasitism = One species benefits at the expense of another
Match the example with the ecosystem interaction:
Hawks, wolves, lions = Predation Bees and flowers = Mutualism Competing for limited resources = Competition N/A = Commensalism
Match the term with its definition:
Facultative mutualism = Mutualistic relationship that is optional for survival Obligate mutualism = Mutualistic relationship necessary for survival Diffusive mutualism = Mutualistic relationship where benefits spread through a community N/A = Commensalism
Match the interaction type with its impact on species involved:
Both benefit = Mutualism Both negatively affected = Competition Predator benefits, prey harmed = Predation N/A = Commensalism
Match the following types of competition with their definitions:
Interference competition = Involves direct conflict between individuals Exploitative competition = Involves indirect resource depletion Predation = A symbiotic relationship where one species benefits while the other is harmed or killed Mutualism = A symbiotic relationship where both species benefit
Match the following terms with their correct descriptions:
Parasitism = One species benefits while the other is harmed or killed Ectoparasites = Parasites living on the surface of the host Endoparasites = Parasites living inside the host Commensalism = One species benefits while the other is neither harmed nor benefited
Match the examples with the correct type of interaction:
Wolves hunting deer = Predation Fleas, leeches, tapeworms = Parasitism Bird perching on a branch = Commensalism Barnacle attaching to a whale for transportation = Commensalism
Match the following types of commensal associations with their descriptions:
Inquilinism = One species benefits without affecting the other Chemical commensalism = Chemical interaction benefiting one species Phoresy = Transportation benefit for one species Metabiosis = One species benefits from another after its death
Match the following statements with the correct type of interaction:
Both species benefit = Mutualism Only one species benefits, the other is harmed or killed = Parasitism One benefits while the other is neither harmed nor benefited = Commensalism Involves direct conflict between individuals = Interference competition

Ecosystem Interactions: Understanding Predation, Mutualism, Competition, Parasitism, and Commensalism
Ecosystems are complex networks of interactions among various species. These interactions are fundamental to the functioning of ecosystems and can be classified into several types. In this article, we will delve into the subtopics of predation, mutualism, competition, parasitism, and commensalism to understand their roles in ecosystems.
Predation
Predation is an interaction in which one species, the predator, consumes another species, the prey. This interaction benefits the predator, but it is harmful for the prey. Predators are often larger and more powerful than their prey, and they use various adaptations to capture and kill their victims. Examples of predators include hawks, wolves, and lions.
Mutualism
Mutualism is a symbiotic relationship in which both species involved in the interaction benefit. These interactions can take place in three patterns: facultative mutualism, obligate mutualism, and diffusive mutualism. Examples of mutualistic relationships include pollination through bees and flowers, where the bee collects nectar and spreads pollen, and the flower receives pollination.
Competition
Competition occurs when two or more species use the same limited resource and compete for it. This interaction negatively affects both species involved, as either species would have higher survival and reproduction if the other was absent. Competition can be classified as interference competition or exploitative competition, depending on whether it involves direct conflict between individuals or indirect resource depletion.
Parasitism
Parasitism is a symbiotic relationship in which one species, the parasite, benefits from the other species, the host, and is harmed, but not necessarily killed. The host is typically not benefited, and in some cases may be harmed or killed. Parasites can be classified as ectoparasites (living on the surface of the host) or endoparasites (living inside the host). Examples of parasites include fleas, leeches, and tapeworms.
Commensalism
Commensalism is an imbalanced type of interaction in which one species benefits while the other is neither harmed nor benefited. There are four types of commensal associations: inquilinism, chemical commensalism, phoresy, and metabiosis. Examples of commensalism include a bird perching on a branch without affecting the tree and a barnacle attaching itself to a whale for transportation.
These five types of interactions are crucial for understanding the dynamics of ecosystems. They shape the distribution of species, influence population growth, and determine the structure and function of ecosystems. By understanding these interactions, we can better appreciate the intricate relationships that exist among species and the role they play in maintaining the delicate balance of ecosystems.
Test your knowledge on the different types of ecosystem interactions such as predation, mutualism, competition, parasitism, and commensalism. Understand how these interactions shape ecosystems and influence species dynamics.
