<span>Protists obtain food in 3 ways. They produce their own
organic molecules, ingest, and absorb.
Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a
food vacuole around the food item. Inside the food vacuole, enzymes digest the
food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place
through diffusion. Absorptive protists play a key role in decomposition. They are
considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.</span>
Answer:
Option B, Most communities never become completely stable
Explanation:
In an ecological succession, most of the species are unstable and they keep on changing continuously. The succession is primarily of two types –
a) Primary Succession – In this, community of species occur on a new habitat which had been never occupied earlier. Or it can be said that it is entirely a new habitat.
b) Secondary Succession – In this, community of species occur in a habitat where earlier life existed but it was disturbed or damaged by some environmental condition.
Hence , the correct answer is option B
