Question 1

competition definition

Answer 1

integration has negative effects on both individuals

Question 2

competition can be inter and intra specific. what does this mean

Answer 2

inter specific = competition between diffferent species

intra specific - competition within the same species

Question 3

how can intraspecific competition be density dependent?

intraspecific competition negatively impacts ____ and _____ rates ‘

it can lead to _____ and _______

Answer 3

more people = less food resources leftover

growth and reproduction rates

resource partitioning and speciation

Question 4

exploitative (scramble) vs interference competition

Answer 4

exploitative: less resources = everyone gets less

interference: less resources = interfere with other peoples ability to get food so you can have more

Question 5

how does competition affect spatial patterns

Answer 5

T. latifolia stays at shallow waters, T. angustafolia stays at deeper waters. if we were to remove T. latifolia, the T. angustafolia would spread out into the newly-cleared shallow area

Question 6

how can species avoid intraspecific competition?

Answer 6

SPECIALIZING

• if their friends make a net with big holes, this guy makes a net with small holes = catch different food than friends
• so while they’re all fighting for the same food, the guy has his own different food

Question 7

what is mututalism

Answer 7

both species have a positive effect on one other

Question 8

mutualism requires ______ and _______

Answer 8

co-evolved systems
organisms capable of complex behaviors

Question 9

what is facilitation and give an example with crayfish and cladophora

Answer 9

one-directional, positive effect of one species on another (indirect benefit)

cladophora makes thick mats that exclude diatoms. but crayfish graze these mats to eat, but the grazing clears up space for diatoms to grow
