added ecology notes

Question 1

some organisms are able to make their own food by using

Answer 1

elements in the environment and example is photosynthesis

Question 2

autotroph

Answer 2

producers of energy

Question 3

heterotrophs

Answer 3

obtain energy from eating other organisms and they consume others

grass -> cow -> human(2nd order consumer)

Question 4

decomposers

Answer 4

Break down organic matter

ex bacteria and fungi

Question 5

as we move up feeding levels to the top consumers

Answer 5

we lose available. Energy

Question 6

with every passing level how much energy is lost

Answer 6

90% of all energy is lost

Question 7

exponential growth occurs when

Answer 7

The number of organisms increase by an ever increasing rate and it’s J shaped and there are unlimited resources

Question 8

logistic growth

Answer 8

A populations growth slows or stops following a period of exponential growth this is S shaped

Question 9

carrying capacity

Answer 9

The number of organisms of one species that a habitat or environment can hold

Question 10

limiting factors

Answer 10

biotic or abiotic factors that restrict or prevent the existence numbers reproduction or distribution of organisms

Question 11

density dependent factors

Answer 11

factors that limit the size of a population and only exist because the size of that population got two big it is competition

Question 12

density independent factors

Answer 12

limiting factors that would affect all populations regardless of their size or crowdedness

Question 13

carbon cycle

Answer 13

photosynthesis and cellular respiration drive this
