In one paragraph explain how plants get their food and what plants use food for.
Answers
Answer:
Photosynthesis is defined as the process in which the chlorophyll-containing plant
cells synthesise food in the form of carbohydrates, using carbon dioxide and water
in the presence of solar energy.
Sources of raw materials required for photosynthesis:
(a) Water is taken in from the roots of the plant and is transported to the leaves.
(b) Carbon dioxide from the air enters the leaves through the tiny pores called
stomata .
(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is
used to synthesise (prepare) food from carbon dioxide and water.
Thus, photosynthesis can be represented by the following equation.

Answers
Answer:
The correct answer is - the more specialized pharyngeal jaws are for one diet, the less adapted they are for the ingestion of other foods
Explanation:
Pharyngeal jaws are also called throat jaws and are specific for the prey. These jaws have strong muscles and plastic or easy-to-modify teeth. If an organism has pharyngeal jaws specialized for a specific diet or prey it will have lesser chances to adapted well according to the new diet. For instance, pharyngeal jaws highly specialized for scale eating will not be able to adapt well if the fish ingests algae.

Answers
The plants releases oxygen as a byproduct of photosynthesis. this oxygen molecules diffuse through the atmosphere which are inhaled by birds. The correct option is B.
What is photosynthesis?Photosynthesis is the process of making their own food by plants using carbon dioxide and water in the presence of sunlight and chlorophyll.
During photosynthesis, plants release oxygen as a byproduct which diffuses in the atmosphere and get inhaled by the organisms.
Photosynthesis' principal role is to transform sunlight into chemical energy and then hold that chemical energy for later use. This process powers the majority of the planet's living systems.
Photosynthesis is the process by which water and carbon dioxide are converted into glucose and oxygen. The plant consumes glucose as food and produces oxygen as a waste product.
Cellular respiration is the process by which glucose and oxygen are converted into water and carbon dioxide. Water and carbon dioxide are byproducts of the process, and ATP is the energy that is produced.
Thus, the correct option is B.
