Question 2

Name the 2 types of Succession

Answer 2

Primary Succession

Secondary Succession

Question 3

Primary Succession

Answer 3

Occurs in areas where there is no soil

Question 4

Secondary Succession

Answer 4

The gradual change was seen in plant life where soil already has been established

Question 5

3 things in the plant structure include…

Answer 5

Roots
Stems
Leaves

Question 6

Why are roots improtant?

Answer 6

Important in anchoring the tree as well as for the uptake of water and minerals

Question 7

Why are stems improtant?

Answer 7

Brings water and nutrients to the leaves and carries food back to the roots. They also support the plant.

Question 8

Why are leaves improtant?

Answer 8

Essential for using the sun’s energy to make sugar from CO2 and water in the process of photosynthesis
Allows water ti evaporate–> transpiration
