​

Answer 1

Answer:

that is your u told to draw pyramid that one only pyramid

Answer 2

Answer:

The answer is given below.

Explanation:

• Pyramid of number:- there are 4 trophic levels in pyramid of number and each trophic level includes all the organism of that category.

in grassland ecosystem pyramid of number is upright.

1. Primary producer is base of the pyramid which is generally more in number and these produce their own food.
2. Primary consumer is the next one as we go towards apex of pyramid and it feeds on primary producers.
3. Secondary consumer is next one and it feeds on primary consumer
4. Tertiary Consumer is next one and it feeds on secondary consumer.

As we go towards apex of pyramid the number of organisms at each trophic level decreases.

• Pyramid of biomass :- there are 4 trophic levels in this pyramid and it is based on dry weight of the organism. Pyramid of biomass is upright in forest ecosystem and inverted in aquatic ecosystem.
• Pyramid of energy:- it is always upright and has 4 trophic levels. it can never be inverted because that will violate the 10% energy law.
