B represents the growth shown in plants without fertilizer even in similar conditions. Experiment B is important because it helps bring the experiment to a conclusion that plants react better with fertilizer when growing in it’s early stages.
Answer:
Option B, They generally focus on one target insect to ensure that the target insect population remains low.
Explanation:
Biological pest control methodologies are focused towards a specific species of pest and do not harm the non-targeted species. These methods are environment friendly and do not produce any harmful residues. Also they do not develop any kind of resistance in species due to which the same bio pesticide can be used again and again. Since these methods have high specificity, they may require usage of two or more bio pesticides all together.
Hence, option B is correct
Answer:
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
Explanation:
The moon appears to change its shape during the revolving around the earth. This change in the shape of the moon takes place due to the fact that the moon does not have its own light and it reflects light from back to us on the earth.
The moon changes its shape on the basis of how much-reflected light or moon we can see and how much of the moon is facing the sun.
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
Answer:
There is no diagram in this question, however, the question can be answered based on general understanding.
Light energy is converted to chemical energy by PLANTS (GRASS) i.e from the sun to grass
Explanation:
This question is trying to depict a food web or chain of organisms feeding on one another in order to obtain energy. However, in this process, only one organisms amongst the list of organisms is capable of converting LIGHT energy to CHEMICAL ENERGY.
This organism is called a PRODUCER and it is the GRASS (plant). Green plants like the grass in this question are autotrophs i.e. are capable of producing their own food via the process of PHOTOSYNTHESIS. In this process of photosynthesis, plants capture light energy from the sun and convert it to chemical energy stored in sugars.
