Q

What are HERBIVORES???

A

1.) mostly feed on JUST PLANTS
2.) an organism that mostly feeds on plants

18
Q

what are examples of HERBIVORES???

A

rabbits, cows, goats, sheep’s

19
Q

CELLULAR RESPIRATION…??

A

chemical reactions that break down glucose(sugars) to produce ATP
((organisms use oxygen to release this chemical energy of sugars to release carbon dioxide and water))

20
Q

What are CONSUMERS?

A

organisms that rely on other organisms for energy and nutrients

21
Q

What level are consumers at??

A

UPPER TROPHIC LEVELS

22
Q

What is CHEMOSYNTHESIS?

A

(BACTERIA) involve the use of energy released by (inorganic chemical) reactions to produce food.

23
Q

What is PHOTOSYNTHESIS???

A

primary producers use sunlight to convert CO2 and H2O(water) into sugars releasing oxygen

24
Q

What are Primary Producers??

A

capture energy from the sun storing it into sugars and making energy for the community

Capable of producing their own food

25
Q

What is a FOOD CHAIN???

A

a linear series of feeding relationships

(a small fish eats algae, a large fish eats smaller fish, a bird eats larger fish, and an alligator eat the bird

26
Q

What is a POPULATION SIZE???

A

the number of individuals in that population

27
Q

Population DENSITY ??? :PP

A

the # of individuals within a population per unit area

28
Q

Population DISTRIBUTION??

A

how organisms are arranged within an area

29
Q

AGE STRUCTURE?

A

the age a person is and categorized in that group
(age distribution describes the relative #’s of organisms of each age structure populations

30
Q

What is a Sex RATIO»»????

A

males:females
Fingers:TOES

a populations proportion of males to females

31
Q

What is a sign of a healthy population in population size?

A

when a population size (INCREASES OR REMAINS STEADY)

32
Q

Ecologist use what method to count each organism?

A

Sampling Methods

33
Q

If a population size begins to ________________ rapidly, this can be a signal of extinction coming…….

A

DECLINES

34
Q

A population’s density describes how….?

A

big it is

35
Q

What is used with population size to calculate population density?

A

AREA

36
Q

How does HIGH Population Density help a population?

A

it helps organisms to find mates an group together

37
Q

How can HIGH Population Density be harmful?

A

overcrowded population causes competition in resources

38
Q

What is Random Distribution?

A

individual organisms are arranged within a space in no particular pattern

39
Q

What is a Clumped Distribution?

A

individuals arranged around sources of resources

40
Q

What is a Uniform Distribution?

A

individual organisms are evenly spaced throughout an area
