Question

The parasitic and saprotrophic modes of nutrition do not need the three processes required by holozoic animals. Which processes are these? ________________________________________

Answer 1

Answer:

this is heterotrophic mode of nutrition

holozoic

saprophytic

symbiotic

parasitic

Answer 2

Saprotrophs and Parasites do not involve ingestion, digestion or egestion

Explanation:

3 types of heterotrophic nutrition are:

• Saprotrophic nutrition
• Parasitic nutrition
• Holozoic nutrition  

Saprotrophs feed on dead or decaying organic matter.

Parasites obtain nutrition from other living organisms on which they live in, without killing them. They are called hosts.

Holozoic nutrition involves eating solid food, whether plant or animal product.

The five steps to process nutrition in animals are

1. Ingestion
2. Digestion
3. Absorption
4. Assimilation
5. Egestion

Saprotrophs and Parasites do not involve ingestion, digestion or egestion. They just absorb and assimilate.
