Question ask “ which part of the ecological pyramid is incorrect.”

Primary producer

Explanation:

The part of the ecological pyramid which is incorrect is primary producer. Because producers are only producers there is no division of producers as primary or secondary.

so this part of pyramid is incorrect. Producers use energy from the sun and make food for itself and other living parts of the ecosystem.

Hence, the incorrect part is primary producer it should be producer only.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
