3-animals with simple body plans have a digestive compartment with one opening, whereas organisms with complex body plans have digestive tubes with two openings.

Explanation:

Here is the complete question

Q1:A main difference between organisms with simple body plans and those with complex body plans is that

1-animals with simple body plans can ingest food while earlier meals are still being digested, whereas animals with complex body plans cannot.

2-animals with simple body plans have digestive tubes with specialized compartments, whereas animals with complex body plans do not.

3-animals with simple body plans have a digestive compartment with one opening, whereas organisms with complex body plans have digestive tubes with two openings.

4-animals with simple body plans eliminate undigested food via an anus, whereas animals with complex body plans eliminate undigested food via a mouth.

5-animals with simple body plans have digestive tubes with two openings, whereas organisms with complex body plans have a digestive compartment with one opening.

Explanation

This because animals with simple body plans like amoeba have one opening for ingesting and egesting food and waste product. Their digestive compartments thus have only one opening. Whereas, animals with complex body plans like man, have a digestive system which has two openings. One at the anterior of the organism which is its mouth and the other at its posterior which is its anus. The mouth is used for ingesting food while, the anus is used for egesting waste food products.
