Explanation:

To prove the necessity of carbon dioxide in photosynthesis following steps need to do

Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.

Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.

Leave the plant sunlight.

After few hours, perform a starch test to this and another leaf of the same plant.

Observation-

Leaf exposed to the atmosphere are bluish black.

Leaf exposed to KOH does not change to blue-black colour

Result- Starch is present in the green part of the leaf.

Conclusion- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.

Which food chain sequence can be found in this meadow?

Vikki [24]

Answer:

The correct answer is "grass -> grasshopper -> raccoon -> wolf"

Explanation:

Food chains are diagrams that represent the order at which organisms feed from each other, starting from producers that are able to make their own food, until quaternary consumers that feed from predators. In this case, the sequence of grass -> grasshopper -> raccoon -> wolf can be found in the meadow. Grass is a plant that function as producer, which is consumed by grasshopper (primary consumer), which is consumed by raccoon (secondary consumer), which is consumed by wolf (tertiary consumers). I attached the missing information in a picture.
