The answer that you are looking for is True.
Autotrophs and Heterotrophs benefit each other by providing raw materials for various life processes ,directly or indirectly .
Explanation:
- Autotrophs can prepare their own food by using sunlight .This is not possible for Heterotrophs. Heterotrophs obtain their food from Autotrophs.
- Heterotrophs Feed on Plants and helps them in Pollination and Seed dispersal.
- Autotrophs Carry out photosynthesis and produce oxygen which is taken up by heterotrophs for respiration. Heterotrophs in turn, give out Carbon dioxide which is used up by autotrophs.
- Heterotrophs like detrivores and decomposers obtain there food from decaying plant parts and thus break down the nutrient which is then made available to plants.
Pollen , coal and stems are evidences that plants existed in Antarctica.
Explanation:
- Pollens being highly resistant to temperature changes due to the presence of sporopollenin must have remained preserved in ice covered continent of Antarctica.
- Pollens are reproductive units of Plant that suggest existence of plants in the Ice covered land.
- Coal is formed as the fossilization of plants under anaeorobic conditions and high pressure. thus, this also suggest the existence of plants.
- Stems are plant parts thus clearly is an evidence that plants existed there.
