| Ecosystem | a community including the physical aspects of its habitat (soil, water, weather)
🗑
|
||||
| Biotic factors | are organisms in a habitat
🗑
|
||||
| Abiotic factors | are the physical aspects of a habitat
🗑
|

🗑
|
||||
| Consumers | all other organisms that consume plants or other organisms to obtain energy (heterotrophs)
🗑
|
||||
| Decomposers | they eat the remains of dead plants and animals and create biomass.

||||
| Competition | the struggle for resources (Animals: food, water, territory, mates) (Plants: light, minerals, water, space) in an ecosystem
🗑
|
||||
| Interspecific competition | competition that occurs between members of different species.
🗑
|
||||
| Intraspecific competition | competition that occurs between members of the same species.
🗑
|
||||
| Predation | a relationship between two organisms in which one organism kills (predator) and devours another organism (prey).
🗑
|
||||
| Symbiosis | a close long term relationship between two or more species that can be beneficial or harmful
🗑
|
||||
| Mutualism | both organisms benefit from the relationship.
🗑

🗑
|
||||
| Commensalism | one organism benefits, the other organism is neither harmed or help
🗑
|
||||
| Succession | the somewhat regular progression of species replacement
🗑
|
||||
| Primary succession | when species begin to inhabit a place where life has not existed before
🗑
|
||||
| Secondary succession | when species take over areas that have had previous growth
🗑
|
||||
| Pioneer Species |
🗑
|

🗑
|
||||
| What are abiotic factors in an ecosystem? | The nonliving parts, sun, water, dirt, rocks, temperature, etc.
🗑
|
||||
| What are the biotic factors in an ecosystem? | All of the living organisms in an ecosystem, animals, and plants
🗑
|
||||
| An organisms role in an environment is called a | niche
🗑
|
||||
| What are the three ways an organism interacts with it’s ecosystem? | competition, predation, and symbiosis
🗑
|
||||
| The struggle for natural resources in an ecosystem is called | competition

||||
| As populations rises in an ecosystem, competition does what? | rises
🗑
|
||||
| As Competition rises in an ecosystem, populations will | decrease
🗑
|
||||

🗑
|
||||
| What are the three forms of symbiosis? | mutualism, parasitism, commensalism
🗑

||||
| Interaction between two organisms where one benefits and one just doesn’t care | commensalism
🗑
|
||||
| Ecology | the study of the interactions of living organisms with one another and with their physical environment
