Question

Write differences between (AS1)
a) autotrophic nutrition - heterotrophic nutrition
c) Light reaction - dark reaction
b) Ingestion - digestion
d) Chlorophyll - chloroplast​

Answer 1

Answer:

1)ANSWER

ANSWERAutotrophic nutrition andHeterotrophic nutrition

Organism prepares its own food. Organism depends on other organisms for food.

Organism prepares its own food. Organism depends on other organisms for food.Food is prepared from carbon dioxide and water in presence of sunlight. Food cannot be prepared from carbon dioxide or water.

Food cannot be prepared from carbon dioxide or water.Green plants and certain bacteria like blue green algae have autotrophic nutrition. All the animals, most bacteria have heterotrophic nutrition.

Autrotrophs are producers in the food chain. Heterotrophs are consumers in the food chain.

2)What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.

3)Ingestion is taking food into the mouth for example. Digestion is when the ingested food is now broken down into smaller building blocks. This may be achieved by mechanical means (chewing, churning) and chemical means (digestive enzymes of stomach and intestines).

4) Difference Between Chlorophyll and Chloroplast

Difference Between Chlorophyll and ChloroplastMainly, chlorophyll absorbs red and blue light from the sun converting it into chemical energy but chloroplast is a part where photosynthesis takes place.
