While on a field trip near the ocean coastline, you visit a company that harvests jellylike substance from protists. This substance can be used as food, or in biology lab dishes for culturing organisms that have red-blue pigments, and store starch like plants. The company extracts the substance from multicellular plant-like organisms. You are observing the economic values of
(A) algin.
(B) gelatin.
(C) carrageenan.
(D) red ooze.
(E) agar.

Agar

Explanation:

In the given question, the substance obtained from a multi-cellular organism with its plant-like and stores starch like a plant is the algae.

Many useful substances are obtained from these algae whose characteristics are given are like they are jelly-like, used as food, used to grow the cultures of organism shows the properties of a chemical called agar.

Agar is obtained from the species of genus Gelidium and the Gracllaria red algae which are plant-like organisms.

Thus, agar is the correct answer.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
