Question

Match the following organisms with their mode of nutrition.

Answer 1

• Organisms which use a saprotrophic mode of nutrition are called saprotrophs. Monotropa and mushrooms are examples of saprotrophs.
• Cuscuta is an example of a parasitic plant. They do not contain chlorophyll. They derive nutrition from other plants called the host plant. Hence, it is an example of a total parasite.
• Insectivorous nutrition is the mode of nutrition in which plants feed on insects to fulfill the requirement of nutrients like nitrogen. They contain chlorophyll and can perform photosynthesis. However, they grow in soil which is poor in nutrients. Hence, they feed on insects. Sundews are an example of insectivorous plants.
• Partial parasites are those that depend on their host for only water and minerals but do not depend on them for food.Such plants contain chlorophyll and can perform photosynthesis. Loranthus is an example of a partial parasite that depends on the host plant for water and minerals.
