Define the biological species concept. A species is a living organism which follows the biological species concept of parasitism‚ commensalism‚ and mutualism. The biological species concept: Parasitism: one benefits from the other; taking over a host‚ (+/- reaction) (Ex: plasmodium apicomplexa taking over a human host causing malaria‚ tapeworm) Commensalism: one benefits and one doesn’t care‚ (+/0 reaction) (Ex: barnacles and whale the barnacles stuck themselves on the whales front side

another organism (prey) * Symbiosis: any relationship in which 2 species live closely together. There are 3 main kinds of symbiosis: 1. Mutualism 2. Commensalism 3. Parasitism Mutualism: a situation when both organisms benefit from a relationship Examples: a bee and a flower; a sea anemone and a clown fish Commensalism: a situation when one species benefits and one is not affected Example: a shark and a remora Parasitism: a situation in which one organism

of different species of organisms. Many people associate symbiosis with mutualism‚ interactions that are beneficial to the growth‚ survival‚ and/or reproduction of both interacting species. But symbiotic interactions also include commensalism (one species receives benefit from the association and the other is unaffected)‚ amensalism (one species is harmed‚ with no effect on the other)‚ and parasitism. An example of commensalism is found in the anemone fish‚ which gains protection from living among

Which means the dog may take in the litter of kittens‚ and the act of commensalism would be present. While the kittens are receiving care‚ food‚ and protection‚ the dog is receiving nothing‚ but parental instinct makes the dog want to care for the kittens. Therefore‚ a relationship where a

In economics‚ a compensatory test is applied for “evaluating public policy choices” (Kenyon 258). The test compares existing policies to suggested policies and the suggestion is only accepted if the prospective gainers can compensate prospective losers without leaving any individual worse off (Chipman). So‚ what if this test were used to evaluate “policies involving the gain or loss of human life” (Kenyon 258)? In such a scenario‚ it may be proposed that society could only continue to benefit because

relationship in which a predator captures and eats its prey. Competition is when more than one organism (or population) tries to use the same limited resource. Symbiosis is a relationship between two species. Mutualism‚ commensalism‚ and parasitism are the three main types of symbiosis.

The anemone is benefited in the situation by being able to eat particles of food that the boxer

Competition- (–/– interaction) occurs when species compete for a resource in short supply example when an invasive species moves in it cause competition.
