Answer:
<h2>Digestion in sponges is intracellular.
</h2><h2>Cnidarians carry out extracellular digestion
.</h2>
Explanation:
digestive process in cnidarians differ from sponges
1. i) sponges have intracellular digestive system.
ii). They feed on planktons by filtering water.
iii). Digestion takes place completely in choanocyte cells.
Cnidarians
1. i) Cnidarians are predators and feed on small fish, krill and many small species.
ii )All cnidarians are carnivores and have very simple body structures adapted as predators.
iii) Cnidarians carry out extracellular digestion. Enzymes break out the food into small particles. Cnidarians have an incomplete digestive system and have only one opening.
Answer:Mostly the stars, planets and heat

Answer:
The livestock species play very important economic and socio-cultural roles for the wellbeing of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production. The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro, namely in a mountain area, an irrigation plain and a coastal zone, and were complemented with secondary data. Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species. Beyond the economic function, each livestock species also performs social and cultural functions.

The respiratory pigment you would find in a
blue crab or octopus is hemocyanin. emocyanins are respiratory proteins occurring extracellularly in
the hemolymph of some arthropods and molluscs. Although the hemocyanins<span> from both
stems have a similar oxygen-binding center, they have different structures.</span>
