Answer 25

They can make their own energy.

Question 26

Consumer

Answer 26

Eat other organisms.

Question 27

Trophic level

Question 28

Decomposer

Answer 28

Breaks down dead or decaying matter.

Question 29

Primary consumer

Answer 29

Any consumer that is eating the producer is a primary consumer.

Question 30

Secondary consumer

Answer 30

A secondary consumer is a consumer that eats the primary consumer.

Question 31

Tertiary consumer

Answer 31

A tertiary consumer is a consumer that eats the secondary consumers.

Question 32

Quaternary consumer

Answer 32

The last level is a quaternary consumer eats the tertiary consumer.

Question 33

Germination

Answer 33

The term germination is the process of a coated seed growing a root and beginning to grow into a plant

Question 34

Seedling formation

Answer 34

It starts growing towards sunlight when it gets the proper nutrients from the sun as well from the roots.

Question 35

Growth and development

Answer 35

Plants carry out a process called photosynthesis using sunlight, carbon dioxide, and water to synthesize their own food in the form glucose.

Question 36

Differentiation

Answer 36

Plants become a mature plant and starts flowering. Flowers will attract bees and pollinate insects and helps in pollination and fertilisation.

Question 37

Pollination

Answer 37

Pollination occurs when pollen travels from one plant to the flower of a different plant.

Question 38

Fertilisation

Answer 38

Fertilisation is when the pollen meets the egg inside the flower. This creates seeds!

Question 39

Volcanic eruptions

Answer 39

Release large amounts of carbon dioxide into the atmosphere.

Question 40

carbon sequestration
(on land)

Answer 40

On land, plants take in carbon dioxide to use in photosynthesis and store within their tissues (cells).

Question 41

carbon sequestration
(in ocean)

Answer 41

phytoplankton and other marine organisms take in carbon through photosynthesis.

Question 42

cellular respiration

Answer 42

Animals eat the plants and take in 02 to power cellular respiration, and the release c02 into the atmosphere. Works with photosynthesis to act as carbon transfer between organisms.

Question 43

photosynthesis

Answer 43

Plant cells absorb solar energy, carbon dioxide and water and convert them into oxygen, water and glucose (energy). Works with cellular respiration to act as carbon transfer between organisms.
