Scientific understandings of the outdoors

Question 1

Producers

Answer 1

Through the process of photosynthesis, PRODUCERS (Autotrophs) manufacture complex inorganic substances, generally CO2 and H2O – using the energy of sunlight to do so.

Question 2

Consumers

Answer 2

Animals are CONSUMERS, (heterotrophs) that is they use the bodies of other organisms as a source of food energy.

Question 3

Decomposers

Answer 3

DECOMPOSERS breakdown organic material and use the decomposition products to supply themselves with energy

Question 4

Food chains and food webs

Answer 4

A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web.

Question 5

Biotic

Answer 5

Living things

Question 6

Abiotic

Answer 6

Non-living things

Question 7

Subsystems

Answer 7

Ecosystems are made up of subsystems that interact with each other. These are largely made up of the abiotic and biotic components.

Question 8

Atmosphere

Answer 8

The gas that surrounds the earth. We rely on this for Nitrogen, and O2 - and we are the only planet that is known that has O2 to sustain us.

Question 9

Hydrosphere

Answer 9

all the water on earth

Question 10

Lithosphere

Answer 10

The soil and rocky crust of the earth and it’s core of molten rock.

Question 11

Organism

Answer 11

Refers to single living thing

Question 12

Species

Answer 12

Is a group of organisms of the same type that are capable of interbreeding.

Question 13

Population

Answer 13

Is a group of organisms of the same species living together in the one area.

Question 14

Community

Answer 14

Consists of a number of populations of different species living together in an environment

Question 15

Habitat

Answer 15

Refers to the specific place within an ecosystem that is occupied by an organism or population

Question 16

Water cycle

Answer 16

Precipitation
Collection
Evaporation & Evapotranspiration
Condensation

Question 17

Carbon cycle

Answer 17

Plants absorb carbon dioxide during photosynthesis.
Turning it into glucose & starch, allowing them to function properly and maintain their structure.
The carbon passes up the food chain.
Then through respiration & decomposition, it is recycled back into the atmosphere.
It is also found underground in fossil fuels and when burned in industrial processes, contributing to carbon levels in the atmosphere.
