Q

What is sampling? A quadrat equation?

A

Sampling- estimating by counting individuals in smaller area and x by a larger area
Quadrat: take random areas in large area, count individuals in each area and +, then ÷ total by no. of samples to = average /square, multiply average by total no. of squares= approx. no. of animals in large area.

Q

What is a canopy?

A

treetops shielding/covering from the sky

21
Q

What does arid mean?

A

little to no rain

22
Q

What is a biosphere?

A

everyplace on Earth where all living and non-living things interact with each other

23
Q

What are the 3 parts of the biosphere? Explain each part.

A

Hydrosphere- water
Atmosphere- Air
Lithosphere- Land

24
Q

What is succession? Examples?

A

gradual process where certain species take over and replace original ones

25
Q

Organisms come first in succession True or False

If no, what happens first?

A

False, Lichens grows and breaks down rocks

26
Q

What happens if non-native species are introduced? Example?

A

native species may not have enough food and next line of succession dies out
Ex. Zebra Mussels

27
Q

What happens if succession occurs too quickly? Example?

A

some organisms may overtake and force them to go extinct

Ex. dodo birds

28
Q

What is the difference between Photosynthesis and Cellular Respiration?

A

Photosynthesis: plants

Cellular Respiration: humans and animals

29
Q

What is the formula for photosynthesis?

A

water + carbon dioxide +(sunlight) = glucose + oxygen

30
Q

What is the formula for cellular respiration?

A

glucose + oxygen = water + carbon dioxide = (ATP Energy)

31
Q

What is a food chain? 3 examples.

A

shows how energy is passed from one organism to another

32
Q

What is a food web? Example if wanted.

A

more accurate than food chain, shows how animals interact(predator, prey)

33
Q

What is a producer vs consumer? Examples?

A

Producer: produces food
Consumers: consumes food made by producers

34
Q

What is the difference between a herbivore, carnivore, and omnivore? Examples of each?

A

herbivore: eats plants
carnivore: eats meat
omnivore: eats both, eats anything

35
Q

What is a predator vs prey? Example?

A

predator- hunts for food

prey- is the food

36
Q

What is a scavenger? Example?

A

eats dead or decaying food

37
Q

What is a decomposer? Example?

A

breaks down dead material and recycles back into ecosystem

38
Q

What is a niche?

A

the role an animal plays in an ecosystem

39
Q

What are some animals who have more than one niche?

A

seagulls- scavenger (dead organisms on shore) and carnivore (fresh fish)
snails- scavenger (dead fish) and herbivore (plants and algae)

40
Q

What is an energy flow?

A

movement of energy

41
Q

What is an energy pyramid? What is the energy used for?

A

show show energy is transfered; energy is used for many things

42
Q

What is a pyramid of numbers?

A

shows how much of each animal/ energy is needed to sustain the other

43
Q

What is biomass? Does it decrease or increase as you go higher in levels?

A

total mass of all organisms in ecosystem

decreases as you go up

44
Q

What is an autotroph vs heterotroph?

A

autotroph: produces food
heterotroph: can’t produce own food

45
Q

What is symbiosis?

A

two species living closely together in relationship that lasts over time

46
Q

What are the 3 types of symbiosis? Examples of each?

A

Parasitism, Mutualism, Commensalism

47
Q

Which is the symbiosis where both benefit?

A

Mutualism

48
Q

Which is the symbiosis where one benefits and the other isn’t affected?

A

Commensalism
