Question

what is the mode of transportation in animals that do not have a transport system?

Answer 1

Animal-powered transport:which is mostly referred to as beast of burden. It is the oldest means of transportation; this usually involves the use of animals for the transportation of people and goods. Humans may ride some of the higher animals directly, or harness them.

Answer 2

Following are the possible modes of transportation in animals that do not have a transport system:

1. Water Vascular/Canal System: Lower phyla like Porifera lack organ systems. They allow water to flow through their body. The water brings food and removes the body's waste.
2. Sinuses: Some animals have an open circulatory system. They lack blood vessels. The blood (or hemolymph) is present in open body spaces called the sinus. The exchange of substance takes place directly between the body fluid and the organs bathed in it.
3. Simple Diffusion: Some animals like amoeba and euglena do not need a transportation system. They exchange substances directly with the external environment through their cell surface via diffusion.
