Food chains go from left to right, food web go from the bottom to the top

Question 12

Define Classification/Taxonomy

Answer 12

The way to define and classify an organism.
Categorising organisms based in their physical characteristics.

What is a community?

Answer 13

All the living organisms that live within a given area and interact with each other.

Question 14

What is an Ecosystem?

Answer 14

An Ecosystem is a biological community of interacting organisms and their physical environment. This includes all the biotic and abiotic factors in a specific region which interact.

Question 15

What is a biome?

Answer 15

A major ecological community of organisms adapted to a particular climatic or environmental condition on a large geographic area in which they occur.

Question 16

Define Biosphere

Answer 16

Broadest level of biological organisation. All life/ organisms on earth, biotic. The regions of the surface and atmosphere of the earth or another planet occupied by living organisms.

Question 17

Rainforests, Deserts, Grasslands, Bushland, Reefs.

Question 24

What are Abiotic and Biotic?

Answer 24

Biotic is Alive and Abiotic is not alive.

Question 25

What are examples of Abiotic factors?

Answer 25

Sunlight, wind, temperature, salinity.

Question 26

What are Heterotrophs and Autotrophs?

Answer 26

A Heterotroph is an organism that has to eat for it's food and energy. (Animals) An Autotroph is an organism that has it's own process and make it's own food without having to eat for it. (Plants using Photosynthesis)

Question 27

Define Producers

Answer 27

Producers are an organism that generated glucose from sunlight via photosynthesis to make energy via cellular respiration.

Question 28

Define a Consumer

Answer 28

Consumers are organisms that consume other organisms to gain glucose and other chemicals to make energy via cellular respiration.

Question 29

Define Decomposers

Answer 29

Decomposers are an organism that breaks down organic material and absorbs other chemical to make energy via cellular respiration.

Question 30

What is a commensalism symbiotic relationship?

Answer 30

One Organism benefits and the other neither benefits or is harmed.

Question 31

What is a mutualism symbiotic relationship?

Answer 31

Where both Organisms benefit.

Question 32

What is a parasitism symbiotic relationship?

Answer 32

One organism benefits and the other is harmed

Question 33

What is a predation symbiotic relationship?

Answer 33

One organism eats the other

Question 34

What is a symbiosis relationship?

Answer 34

Where there is an interaction between two organisms.

Question 35

What is a Biomass pyramid?

Answer 35

It calculates the total quantity or weight of organisms in a given area or volume.

Question 36

What is a population pyramid?

Answer 36

Shows population of each organism in each trophic level.

Question 37

How does Cellular Respiration work?

Answer 37

oxygen + gluecose - energy- carbon + water + APT

Question 38

Where does the extra energy go in Energy Pyramids.

Answer 38

Organisms don't eat every part, the energy doesn't get absorbed, the energy gets released through cellular respiration.

Question 39

What is the difference between Eukaryotic and prokaryotic cells?

Answer 39

Eukaryotic cells have a nucleus (Brain) Which stores DNA, this is all the kingdoms except for bacteria. Prokaryotic cells don't have a Nucleus, this is archaebacteria and Eubacteria.

Question 40

What is the difference between unicellular and multicellular organisms?

Answer 40

unicellular organisms are only made of one cell. Multicellular organisms are made of more than one cell (complex)

Question 41

What are examples of unicellular organisms?

Answer 41

Bacteria and archaea bacteria are unicellular, fungi and protists can be either multicellular or unicellular

Question 42

What are examples of multicellular organisms?

Answer 42

Animals and plants are multicellular, fungi and pro teeth can either be unicellular or multicellular.
