3.1 interactions in marine ecosystems Flashcards
Chlorophyll
A pigment found in plants and algae that is used to absorb sunlight for photosynthesis
Photosynthesis (photosynthetic, photosynthesize)
The process of using light energy to synthesize glucose from carbon dioxide and water to produce chemical energy
Carbohydrate
Organic compounds occurring in living tissues that contain carbon, hydrogen, and oxygen (for example: starch, cellulose, and sugars); carbohydrates can be broken down in the process of respiration to release energy
Consumer
An animal which feeds on other organisms to gain energy from food
Algal Bloom
A rapid increase in a population of algae
Community
All the different populations interacting in one habitat at the same time
Mutualism (Mutualistic)
A relationship between two different organisms where both organisms benefit
Predation
A relationship between two organisms where a predator hunts, kills and eats a prey animal
Parasitism
A relationship between two organisms where the parasite obtains benefit at the expense of the host
Competition
A relationship between two organisms where both species are negatively affected as they are trying to use the same resources
Symbiosis
A relationship between two or more organisms of different species which live physically close to each other
Commensalism
A relationship between two organisms where one organism benefits and the other is neither harmed nor benefitted
Ectoparasite
A parasite, such as a flea or a louse, which lives on the outside of its host
Endoparasite
A parasite, such as a tapeworm, which lives inside the body of its host
Phoresis
A commensal relationship where one organism attaches itself to another in order to travel
