Q

What is ecology?

A

The study of the interactions between organisms and their environment

21
Q

What are ecosystems

A

many different species that interact together to keep their environment in balance

22
Q

What do ecosystems consist of

A

Biotic and abiotic factors

23
Q

What types of ecosystems are there

A

Aquatic and terrestrial

24
Q

What are producers

A

Organisms that make their own food through photosynthesis or chemosynthesis (autotrophs)

25
Q

What are consumers

A

An organism that consumes other organisms for food

26
Q

What are decomposers

A

Organisms that break down the remains of dead organisms and other organic waste

27
Q

What is a food chain

A

how energy is passed on from one organism to the next

28
Q

What is a food web

A

The different interactions between organisms

29
Q

What do symbiotic relationships consist of

A

Mutualism, commensalism, parasitism

30
Q

What is mutualism

A

When both organisms benefit from each other

31
Q

What is commensalism

A

when one organism benefits while the other is not harmed

32
Q

What is parasitism

A

One organism benefits while the other is harmed

33
Q

What are the layers of the pyramid

A

Producers (autotrophs), primary consumers (1st order heterotrophs), secondary consumers (2nd order heterotrophs), tertiary consumers (3rd order heterotrophs)

34
Q

What is trophic level

A

Biosphere, many ecosystems, communities, populations, individual organisms

35
Q

What does photosynthesis do?

A

Provides autotroph with food in the form of glucose. releases oxygen into the atmosphere which is used by eukaryotic cells when going through cellular respiration

36
Q

what does the equation for photosynthesis start with

A

6

37
Q

where does cellular respiration occur

A

mitochondria

38
Q

What does cellular respiration do

A

provides cells with the energy they need to carry out all functions. It releases carbon dioxide into the atmosphere which is used by autotrophs to carry out photosynthesis
