In an environment, organisms can have different types of relationships with each other. The relationship between two organisms depends on what each organism is doing to the other organism.
Here are some common relationships in nature:
This organism gains food or shelter from another organism.
This organism uses parts of another organism in some way.
This organism is eaten by another organism.
These organisms compete with each other for food, space, or other resources.
These organisms are in a symbiotic relationship. The word symbiosis comes from a Greek word that means living together. In a symbiotic relationship, two organisms live together in a way that is helpful to both organisms.
The word parasite comes from a Greek word that means eating alongside. In a parasitic relationship, one organism gets food or other resources from another organism. The second organism is not helped by the relationship.
In a predator-prey relationship, a larger organism hunts and eats a smaller organism. The larger organism gains food and energy. The smaller organism is killed in the relationship.
There can be more than two organisms in a relationship. For example, a herd of antelopes and a pack of lions might live in a ecosystem. The antelopes and the lions have a predator-prey relationship. But the antelopes and the lions are not in a symbiotic relationship. The answer is C.

The relationship between two organisms depends on what each organism is doing to the other organism. Relationships can be classified by what the organisms are doing to each other.
Here are some common relationships between organisms:
A competitive relationship exists when organisms compete with each other. Competition happens when both organisms try to get what they need for survival.
Example: A crop plant and a weed. The crop plant and the weed compete for water, nutrients, and space.
A predatory relationship exists when one organism attacks and eats another organism. A predator gets its food by eating another organism.
Example: A panther and a deer. The panther is the predator. It uses its sharp claws to kill and eat the deer.
A symbiotic relationship exists when two organisms live in a relationship where each organism helps the other. Symbiotic relationships are positive relationships.
Example: A fungus and a tree. The fungus helps the tree by giving it food and water. The tree gives the fungus a place to live.
A parasitic relationship exists when one organism lives off of the resources provided by another organism. The second organism is not necessarily hurt by the relationship.

In nature, animals interact with each other in different ways. How animals interact with each other depends on the types of animals.
Animals that are similar to each other interact in specific ways. Similar animals often live in groups. The group may include multiple individuals related to each other. Or the group may include individuals that are not related to each other.
Animals that are very different from each other may not interact at all. Or they may compete with each other for resources. Competitive relationships describe interactions between animals that are similar but competing for resources.
Animals in competitive relationships may fight each other. But they do not usually die because of these fights. Instead, the strongest animal wins the resource it needs to survive.
Animals that are not related to each other may interact in symbiotic relationships. Symbiotic relationships describe interactions that are helpful to both animals.
Animals in a symbiotic relationship share resources or provide services to each other. For example, a cow cowboy beetle has a symbiotic relationship with a cow. The cow cowboy beetle gets food and shelter from the cow. And the cow gets its hair cut by the cowboy beetle!
Animals that eat each other interact in predatory relationships. Predatory relationships describe interactions between animals that eat each other.
A lion eats its prey. So, the lion and its prey have a predatory relationship. The answer is C.

When two organisms of different species interact in a way that affects one or both organisms, they form a symbiotic relationship. The word symbiosis comes from a Greek word that means living together. Scientists define types of symbiotic relationships based on how each organism is affected.
This table lists three common types of symbiotic relationships. It shows how each organism is affected in each type of symbiotic relationship.
Type of symbiotic relationship | Organism of one species... | Organism of the other species...
Commensal | benefits | is not significantly affected
Mutualistic | benefits | benefits
Parasitic | benefits | is harmed (but not usually killed) When a deer eats a plant, the deer gets food and the plant gets protection from being eaten. This interaction forms a mutualistic relationship. Both the deer and the plant are helped by their relationship.
When a shark bites into a fish, the shark gets food and the fish gets hurt. This interaction forms a predatory relationship. The shark benefits because it gets food. But the fish is harmed.
There are many types of predatory relationships. An animal that eats another animal is called a predator. An animal that is eaten by another animal is called a prey. Companionable relationships are not predatory. A person and his or her pet form a companionable relationship. The answer is C.

In nature, creatures can have different types of relationships with each other. The type of relationship that two creatures have depends on what each creature gets out of their relationship.
Creatures that get food, shelter, or other needs from each other are in predative relationships. Creatures in predative relationships try to eat each other. This activity is called predation.
Creatures that get food, shelter, or other needs from each other are in predatory relationships. Predatory relationships can be classified by the relationship between the creatures.
The creatures in a predative relationship can be divided into two groups:
The group that does the eating is called the predator.
The group that is eaten is called the prey.
Competitive relationships are based on competition for food or other resources.
The creatures in a competitive relationship try to get as much food or other resources as they can. This activity makes it more likely that both creatures will survive.
Symbiotic relationships are based on both creatures benefiting from the relationship.
In a symbiotic relationship, both creatures benefit. The answer is C.
