Biotic factors Biotic factors include all living things and their interactions with other organisms
Abiotic factors An abiotic factor is a non-living part of the environment that affects the lives of organisms.
Ecology Is the study of the relationships between living things and their physical environment.
Parasitism Symbiosis where one species benefits and the other is harmed Example-Mosquito& human
commensal Symbiosis where one species benefits and the other in neither help or harmed Example- shark& Remora
mutualistic Symbiosis where both species benefit Example- bee& flower
symbiosis A close relationship between species that benefit at least one of the species
competition Competition is most typically considered the interaction of individuals that vie for a common resource that is in limited supply, but more generally can be defined as the direct or indirect interaction of organisms that leads to a change in fitness when t
Predator-prey relationship An interaction in which one organism kills and eats the other
photosynthesis The reaction in producers that transforms light energy into chemical energy Photosynthesis produces sugar molecules that store chemical energy to support life processes.
Cellular respiration The reaction in living cells that releases energy for life processes
Lost matter in a food chain (3 examples)
Stored energy Energy is transferred between organisms in food webs from producers to consumers.
heterotrophic A heterotroph is an organism that eats other plants or animals for energy and nutrients.
autotrophic An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
Food web Connected pathways of energy transfer between organisms A food web is built by connecting all the food chains in a particular ecosystem
Food chain One pathway of energy transfer between organisms The arrows in a food chain show the transfer of energy from one type of organism to another
Predator-prey graph A graph showing changes in the numbers of predators and prey
The carbon cycle The continual movement of carbon through ecosystems
Interdependent Living things depend on each other for survival.
Great Pacific Garbage Patch The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean.
Biodegradable (of a substance or object) capable of being decomposed by bacteria or other living organisms and thereby avoiding pollution. Able to be broken down by bacteria or fungi
biomagnification The increase in concentration of a contaminant up through a food chain
omnivore These consumers eat other consumers and producers. Omnivores eat animals and plants. Most humans are omnivores.
decomposer organism that breaks down dead organic material; also sometimes referred to as detritivores.
producer an organism that produces. (makes) its own food
Primary consumer Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else.
Secondary consumer Secondary consumers are largely carnivores that feed on the primary consumers or herbivores
Tertiary consumer Tertiary consumers are those that eats the secondary consumers
