Ecology Quizs

Ecological succession

• The process of change in the species structure of an ecological community over time

• A method of measuring biodiversity in an ecosystem

• The introduction of non-native species into an ecosystem

• The seasonal migration of animals in response to climate changes

Biotic

• Non-living components of an ecosystem

• Living components of an ecosystem

• Physical environment of an ecosystem

• Chemical components of an ecosystem

Population

• A group of individuals of the same species living in a specific area

• A collection of different species in an ecosystem

• The total number of organisms in a habitat

• A group of individuals from different species living together

Photosynthesis

• The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll

• A method of respiration in animals

• The process of water absorption in plants

• The conversion of carbon dioxide into oxygen by animals

Parasitism

• A relationship between two organisms where one benefits at the expense of the other

• A mutual relationship where both organisms benefit

• A relationship where one organism is unaffected while the other is harmed

• A relationship where both organisms compete for resources

Community

• Different populations living together in a defined area

• A group of individuals with similar interests

• A collection of random organisms

• An area with no inhabitants

Symbiosis

• A close and long-term biological interaction between two different biological organisms

• A type of competition between two species for resources

• A process of evolution where species become more similar over time

• A method of reproduction involving two parent organisms

Exponential growth

• Population growth that occurs when resources are unlimited

• Population growth that occurs when resources are limited

• Population growth that occurs at a constant rate

• Population growth that occurs in a linear fashion

Keystone species

• A species that is the most abundant in an ecosystem

• A species that has no significant impact on its ecosystem

• A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically

• A species that is always at the top of the food chain

Decomposer

• An organism that breaks down dead or decaying organisms

• A producer that creates energy through photosynthesis

• A consumer that feeds on living organisms

• A scavenger that collects waste materials
