What is a list of the types of organisms in an eco pyramid?

producer, primary consumer, secondary consumer, tertiary consumer.

Explanation:

Biological pyramid show the relationship between organisms at different level graphically. This organism include producer ,primary consumer, secondary consumer and tertiary consumers.

The green plants and Algae are the producer, they manufacturing their own food through the process of photosynthesis while primary consumer( Herbivore such as goat) feeds on producer to get their own energy.

Secondary consumer (carnivores such as snake) also feeds on the primary consumer and the tertiary consumer such as eagle feeds on secondary consumer. Plant and Algea has the highest energy level while the tertiary producer have the least energy level.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
