16
Q

Pyramid of numbers

A

shows the number of organisms at each trophic level in an ecosystem

17
Q

Biomass

A

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

18
Q

Biomass pyramid

A

graphical representation of biomass present in a unit area of various trophic levels

19
Q

10% rule

A

Only 10% of energy is transferred to the next trophic level 90% is lost through heat

20
Q

Germination

A

refers the start of growth of a plant from a seed.

21
Q

Seedling Formation

A

Process which a fragile plant grows from a germinated seed, towards the sunlight

22
Q

Growth and Development

A

Establishing the seedling’s ability to photosynthesize and grow independently

23
Q

Differentiation

A

The plant develops cells tissues and organs that aid reproduction and growth.

24
Q

Pollination

A

Where pollen from the anther (male part) is transferred to the stigma (female part)

Occurs through wind, water, insects, other animals

25
Fertilization
Where the male pollen fuses with the ovule (male female gamete) within the flower forming a zygote.
26
Formation of fruits + seeds
Zygote develops into an embryo-> transforming into a seed which is inside the fruit. When fruit is ripe seeds are dispersed
