Question 10

Evolution

Answer 10

the gradual development of something, especially from a simple to a more complex form.

Question 11

Producers / autotrophs

Answer 11

They get energy from chemicals or the sun, and with the help of water, convert that energy into useable energy in the form of sugar, or food.

Question 12

Consumers / heterotrophs

Answer 12

are organisms that eat organisms from a different population. These organisms are formally referred to as heterotrophs, which include animals, some bacteria and fungi.

Question 13

Primary consumer

Answer 13

They feed on producers.

Question 14

Secondary consumer

Answer 14

eat these plants exclusively and are all herbivores.

Question 15

Tertiary consumer

Answer 15

a carnivore at the topmost level in a food chain that feeds on other carnivores

Question 16

Herbivores

Answer 16

an animal that feeds on plants.

Question 17

Carnivores

Answer 17

an animal that feeds on flesh.

Question 18

Omnivores

Answer 18

an animal or person that eats food of both plant and animal origin.

Question 19

Decomposers

Answer 19

organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.

Question 20

Food chain

Answer 20

A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species

Question 21

Food web

Answer 21

In food webs, arrows point from an organism that is eaten to the organism that eats it.

Question 22

Energy pyramid

Answer 22

An energy pyramid is a graphical model of energy flow in a community.

Question 23

Carbon cycle

Answer 23

the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

Question 24

Nitrogen cycle

Answer 24

the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

Question 25

Ecological succession

Answer 25

is the process of change in the species structure of an ecological community over time.

Question 26

Primary succession

Answer 26

occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil.

Question 27

Secondary succession

Answer 27

is a process started by an event that reduces an already established ecosystem to a smaller population of species

Question 28

Pioneer species

Answer 28

hardy species which are the first to colonize previously biodiverse steady-state ecosystems.

Question 29

Climax community

Answer 29

is a historic term for a biological community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state.
