ecosystem and photosynthesis

Question 1

ecosystem

Answer 1

all organisms living in a particular area

Question 2

habitat

Answer 2

place where an organism lives

Question 3

population

Answer 3

all the organisms of one species in a habitat

Question 4

population size

Answer 4

number of individuals of one species in a particular species

Question 5

community

Answer 5

all the organisms of diff species that live in the same habitat and interact within each other

Question 6

abiotic factors

Answer 6

non living features

Question 7

biotic

Answer 7

living features

Question 8

reasons for population size to vary because of abiotic factors

Answer 8

abiotic factors such as light, water, temp

Question 9

why does abiotic factors have to be ideal for species

Answer 9

so organisms can grow fast and reprod successfully

Question 10

reasons for biotics factors affecting population size

Answer 10

1) interspecific competition
2) intraspecific competition
3) predation

Question 11

interspecific competition

Answer 11

when organisms of diff species compete with each other for the sme resources

Question 12

limitation of interspecific competition

Answer 12

resources available to both organisms would be reduced, therefore less available, so less energy for food and reprod

Question 13

intraspecific competition

Answer 13

organisms of the sme species compete with each other for the sme resources

Question 14

limitation of intraspecific competition

Answer 14

popu of a species inc when resources are plentiful.
as popu inc, more organisms competing for the sme resources.
resources are limited and popu then begins to decline.

Question 15

predation

Answer 15

where an organisms (predator) kills and eats an another organisms (prey)

Question 16

limitations of predation

Answer 16

as prey popu inc theres more food for predator, so predators popu inc.
when predator popu inc, more prey is eaten, so prey popu dec
so less food for predators, predators popu dec aswell.

Question 17

niche

Answer 17

role of a species within its habitat

Question 18

2 types of succession

Answer 18

primary and secondary succession

Question 19

primary succession

Answer 19

happens on land that is newly formed or exposed such as there’s no soil or organic material to start with just bare rocks

Question 20

secondary succession

Answer 20

happens on land that has been cleared of plants but where soil still remains.
