Which of the statements given above are correct.

2 points

a) 1, 2 and 3 only

b) 2, 3 and 4 only

c) 1 and 4 only

d) All are correct

Answer 1

Answer:

a)

Explanation:

Answer 2

Option D) All are correct.

Explanation:

• An ecological pyramid could be a graphical illustration of the biomass or bio productivity at every organic process level in a very given system.
• Pyramid of the number in the parasitic food chain is inverted because there are very low producers and higher primary consumers that are herbivores.
• Pyramid of Energy in aquatic ecosystems is always upright because the energy level at the base is very high than the consumers at the apex.
• Base of the ecological pyramid is always producers and as we move up we see the consumers at various levels with Apex-Predators at top of it.
