Explanation:
The correct answer is D: holophytically.

A green plant growing in a compost pit is feeding holophytically, which means it is carrying out photosynthesis and synthesizing its own food from inorganic substances (like water and carbon dioxide) using the energy from sunlight. Green plants are autotrophs and obtain nutrients from the soil through their roots, but they primarily feed by photosynthesis.

Here's why the other options are incorrect:
- A. holozoically: Holozoic nutrition is characteristic of animals that ingest and digest food. This is not how plants obtain their nutrients.
- B. parasitically: Parasitic nutrition involves one organism living off another, often harming it. Green plants do not feed this way.
- C. saprophytically: Saprophytic nutrition is when an organism feeds on decaying organic matter, like fungi. While plants may take nutrients from decaying matter in the compost pit, they do not feed in the same way as saprophytes.
- E. in none of the above ways: This is incorrect because plants feed holophytically.

Thus, the green plant is feeding holophytically.
