Competition can occur between organisms of the same species, or between members of different species.

An example of interspecific competition is between lions and leopards that vie for similar prey. Another example is a farm of rice paddies with weeds growing in the field.

For example, two male birds of the same species might compete for mates in the same area.

Therefore, organisms and different species have to find ways to coexist with one another. Several anole lizards in the Caribbean islands share common diets—mainly insects. They avoid competition by occupying different physical locations. Another example is when the mollusks stab their prey with their radula, inject toxins and eat it. Many different species coexist together.]]> 2021-03-08 09:23:28 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1281118544 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282809604 Unlike resource partitioning, The competitive exclusion principle states that no two species can coexist if they occupy the same niche and compete for the same resources. An example of competitive exclusion is, the red squirrels replacing the grey squirrels in Britain. The number of red squirrels decreased because of the disappearance of hazelnuts, competitive exclusion, and diseases. Gray squirrels easily adapted to the environment and replaced the red squirrels gradually.]]> 2021-03-08 15:55:34 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282809604 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282844913 Symbiosis is a close relationship between two different kinds of organisms, or living things. There are three basic types of symbiotic relationships: mutualism, commensalism, and parasitism.]]> 2021-03-08 16:01:09 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282844913 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282894231 Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction.
Example: A relationship between an oxpecker (a kind of bird) and the rhinoceros or zebra. The oxpeckers get food and the beasts get pest control. Another example is symbiotic relationship between a bee and a flower. When bees land on a flower, the bees get some pollen on their hairy bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating the plant. This benefits the plants. In this mutualistic relationship, the bees get to eat, and the flowering plants get to reproduce.]]> 2021-03-08 16:09:04 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282894231 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282925249 It is a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.
Example: 

• Tree frogs use plants as protection. The plant does not benefit and is not harmed.
• Nurse plants are larger plants that offer protection to seedlings from the weather and herbivores, giving them an opportunity to grow.

Example: Tape worms eating & living inside the human flesh, while damaging the human. Another example of parasitism is when fleas or ticks live on dogs and cats. They are living off of the blood of the host animal.]]> 2021-03-08 16:15:59 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282936380 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282985082 predation describes a relationship and actions between two organisms. A predator catches, attacks, and eats its prey. Predators may or may not kill their prey before eating them. However,  the act of predation always causes the death of its prey and taking in the prey's body parts into the predators body.]]> 2021-03-08 16:24:00 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1282985082 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283017057 A predator is an animal that hunts, catches, and eats other animals.
Example, a spider eating a fly caught at its web is a predator, or a pack of lions eating a buffalo.]]> 2021-03-08 16:29:05 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283017057 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283025239 A prey is an animal that is hunted or killed by another animal for food. The animals that the predator hunts are called prey.
Example: mice getting hunted by owls. Another example are worms getting hunted by shrews.]]> 2021-03-08 16:30:22 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283025239 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283070954 mimicry is when a species evolves features similar to another.

An example of Batesian mimicry is the poisonous coral snake and the king snake, which is the mimic. Coral snakes are quite venomous, and their bite is very dangerous to humans and other animals. King snakes, on the other hand, are harmless.]]> 2021-03-08 17:08:18 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283265147 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283280951 Mullerian mimicry, a form of biological resemblance in which two or more unrelated noxious, or dangerous, organisms exhibit closely similar warning systems, such as the same pattern of bright colors. for example, many snakes share auditory warning signals.]]> 2021-03-08 17:10:56 UTC https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283280951 10268216 https://padlet.com/10268216/5ju55yxdpemzmik1/wish/1283295223 Herbivory is the consumption of plant material by animals, and herbivores are animals adapted to eat plants.
