Answer:

Porifera—gastrovascular cavity, coelomate.

Explanation:

Sponges do not contain digestive system but obtain nutrients through the diffusion process. Porifera is the most commonly asymmetrical in nature but can also have radial symmetry. Porifera has no coelom.

Lacking a true digestive system, they depend on the intracellular digestive processes of their choanocytes for their energy intake. Gas exchange, circulation, and excretion occur by diffusion between the water and the cells.

Which practice provides the Best means of protecting biodiversity inthe wild for future generations?? a Initiating recycling pro
PtichkaEL [24]

Answer:

Practice that  provides the best means of protecting biodiversity in the wild for future generations is - <u>expanding breeding programs for endangered species .</u>

Explanation: The best way of preserving biodiversity for future generations in the wild -

  • <u>Expanding breeding programs for endangered species . -:</u> Breeding programmes, such as the panda, help conserve endangered species. Replanting hedgerows because there is greater biodiversity in them than the fields they surround, minimizing deforestation and the release of greenhouse gases, protecting and creating new endangered ecosystems, often by making National Parks.

The other statements are not so suitable means of protecting biodiversity in the wild for future generation as  the first statement indicates about the initiation of recycling programmes in neighborhood , which has no role in preservation of biodiversity or wildlife because the statement is about keeping the environment clean and healthy .

The other statement is about reduction of air pollution as buying vehicles with reduced carbon emissions improves the quality of air.

And the other statement of  Protecting wildlife areas such as national parks comes under the other statement which states "expanding breeding programs for endangered species".

Hence , the correct option is D.
