1

What is ecology?

The study of interactions between organisms and their environment.

2

What are the two types of interactions?

Biotic and abiotic factors.

3

How does temperature impact with how we behave?

Feeling cold/feeling hot is interaction.

4

What are abiotic factors?

Factors that involve non living organisms.

5

What are biotic factors?

Factors that involve living organisms.

6

What are examples of abiotic factors?

water, salt, food, temperature

7

What are biotic factors?

animals and plants

8

What are the four levels of organization?

1. Population
2. Community
3. Ecosystem
4. Biosphere

9

What is a population?

A group of individuals all of the same species living in a particular geographic area.

10

What is a community?

All the populations living in a given area.

11

What is an ecosystem?

The community plus the nonliving environment.

12

What is a biosphere?

All the ecosystems .

13

What is a niche?

The functional role and organism plays in an ecosystem.

14

What are examples of niches?

1. how you interact with the people around you
2. food-what you eat and when you eat it
3. Where you live.

15

What is the survivorship curve?

When there's a low infant mortality and the offspring have a good chance of surviving. Most individuals die of old age. There's a low birth rate and a high level parental care.

16

What is the infant mortality of growth curve one?

Low because they survive well into adulthood.

17

What kind of animal does the 1st growth curve represent?

Humans, dogs, and other higher mammals.

18

What is the birth rate of the survorship curve 1?

low

19

What is the level of parental care in survivorship1?

high

20

What is the rate of death for the second curve?

constant rate of death

21

What are examples of organisms in population curve 2?

small mammals, plants

22

What is the birth rate of survivorship curve 3?

produces a lot of offsprings

23

What is the parental care of 3 like?

little or no parental care

24

What are examples of organisms in 3?

fish, trees

25

What do they produce in large numbers?

Thye produce in large numbers because most of the offsprings die before they are born

26

What is the first growth curve?

exponential growth curve

27

What is the exponential growth curve?

The population grows bigger and faster

28

What is higher in the exponential growth rate?

birth rate

29

Under what circumstance does this circumstance happen?

abundant water
food
no pollution

30

What happens as the population increases?

The population ruins their perfect environment
