Answer 1

Biome, ecosystem, community, population, organism

Question 2

If I had an autotroph what role would it take in the food chain

Answer 2

Producer

Question 3

What is a biome?

Answer 3

A set of ecosystems that share similar characteristics with their abiotic factors adapted to their environment

Question 4

What are the 7 types of biomes?

Answer 4

Tundra, Coniferous forest, Temperate deciduous forest, Temperate grassland, Savanna, Tropical rainforest, Desert

Question 5

What is an ecosystem

Answer 5

The interaction between biotic and abiotic factors in their environment

Question 6

What is a niche

Answer 6

An organisms role in their enviornment

Question 7

A group of organisms from the same species currently living in the same environment

Answer 7

Population

Question 8

Populations that live together in a specific area

Answer 8

Community

Question 9

What are the ecosystem interactions between biotic factors (5)

Answer 9

Parasitism, Mutualism, Commensalism, Predation, Competition

Question 10

What ecosystem interaction is this, when one organism benefits and the other is either harmed or killed

Answer 10

Predation

Question 11

What is the difference between an endo and an ectoparasite

Answer 11

Endo lives within the host and ecto is outside the host

Question 12

Describe commensalism

Answer 12

When one organism benefits (commensal needs this relationship to survive) and the either neither benefits nor is harmed

Question 13

Give an example of mutualism

Answer 13

Flowers and bees

Question 14

Which ecosystem interaction is this, one organism hunts and kills the other

Answer 14

Predation

Question 15

What are the 2 types of competition and describe them?

Answer 15

Intraspecific is competition for limited resources between the same species
Interspecific is between organisms of different species

Question 16

When does competition occur

Answer 16

When there are limited resources and there is an overlap in the organisms niches

Question 17

Organise this trophic level from highest to smallest, secondary consumer, producer, decomposer, primary consumer, tertiary consumer

Answer 17

Tertiary consumer, secondary consumer, primary consumer, producer, decomposer

Question 18

What is a decomposer

Answer 18

Organism that breaks down dead organic matter in the environment

Question 19

What is a decomposer that eats dead organic matter

Answer 19

Detritivore (e.g. flies)

Question 20

What is the difference between a food chain and a food web

Answer 20

A food chain represents only 1 flow of energy but a food web represents many

Question 21

Give me 3 reasons why not all sunlight is used in photosynthesis

Answer 21

Some of the light is reflected, the wavelength is not right, some sunlight doesn’t hit the leaves/chlorophyll

Question 21

Approximately how much energy is passed between each trophic level

Answer 21

10%

Question 22

How can energy be lost between trophic levels

Answer 22

Via respiration and used for metabolic processes, energy is lost to the surroundings, energy lost through bodily secretions

Question 23

What is a pyramid of numbers

Answer 23

They represent the quantity of organisms at each level of a food chain, they can be drawn upright or be inverted

Question 24

Which pyramid is this, tertiary consumers are at the top and it shows the amount of organic material produces at each trophic level

Answer 24

Biomass pyramid

Question 25

What is a pyramid of energy

Answer 25

Producers at the bottom, it shows the energy flow between each trophic level

Question 26

Chemical elements are recycled via the hydrogen cycle and ammonium cycle, true or false?

Answer 26

False The carbon and nitrogen cycle

Question 27

What are some examples of abiotic factors

Answer 27

Atmosphere pressure, water temperature, soil pH, wind speed
