Key terms YR1 & YR2 Flashcards
(60 cards)
What are Abiotic Factors?
Non-living elements of an ecosystem, such as climate, temperature, water, and soil type.
What is Artificial Selection?
Human selection of individuals with desirable traits, such as larger udders or narrower body shape.
What is Biomass?
The dry mass of an organism.
What is a Biome?
A major ecological community of organisms adapted to a particular climatic or environmental condition over a large geographic area.
What are Biotic Factors?
Living elements of an ecosystem, such as plants and animals.
What is a Breed?
A stock of animals or plants within a species having a distinctive appearance, typically developed through artificial selection.
What is Bycatch?
Fish or other marine animals caught unintentionally during fishing, such as dolphins in tuna nets.
What is Carrying Capacity?
The maximum number of organisms an ecosystem can sustainably support.
What is a Carnivore?
An animal that feeds primarily or exclusively on animal matter.
What is Co-Evolution?
The evolution of two or more species which reciprocally affect each other, such as the relationship between a cheetah and a gazelle.
What is Commensalism?
A relationship between two organisms where one benefits, and the other derives neither benefit nor harm.
What is a Community in ecology?
A group of organisms of different species interacting in a specific area.
What is a Consumer?
An organism that obtains its energy by eating other organisms.
What is Convergent Evolution?
The process where organisms not closely related evolve similar traits due to similar lifestyles, such as sharks and dolphins adapting to move through water.
What is Divergent Evolution?
The process by which groups from the same common ancestor evolve and accumulate differences, such as Darwin’s finches.
What is a Domain in taxonomy?
The highest taxonomic rank in biological classification, above the kingdom level, with three domains: Archaea, Bacteria, and Eukarya.
What is an Ecosystem?
A system that includes all living organisms (biotic factors) in an area, along with its physical environment (abiotic factors), functioning together as a unit.
What is Emigration?
The movement of organisms leaving their home due to unsuitable habitat conditions.
What is an Enzyme?
A protein that catalyzes or speeds up a chemical reaction.
What is Evolution?
Biological evolution is the change in species over time through the heritable characteristics of a population.
What is Fecundity?
The maximum potential reproductive output of an individual, typically measured by the number of gametes.
What is a Food Chain?
A sequence of feeding relationships showing which organisms eat what and the movement of energy through trophic levels.
What is Fragmentation?
The process by which large habitats are divided into smaller, isolated patches, also known as habitat fragmentation.
What is a Generalist Species?
A species that can thrive in various environmental conditions and eat a wide variety of foods, often adaptable to new or disturbed environments.
