Answer:
Burning of woods has a negative impact on the climate.
Explanation:
Burning of woods for heating has a negative impact on our climate because it releases carbondioxide gas which is a greenhouse gas that trapped the reflected solar radiation and leads to global warming. We have to used alternative methods for heating such as electric heater instead of burning of wood which produce no pollution and can fulfill the requirement of heating so from the above discussion we can say that the activity has a negative impact on the environment.
Answer: Option 'd' is correct.
Explanation:
Since we have given that
Number of fish caught = 100
Number of tagged fish in catch = 24
So, total number of the fish in the pond is given by
Number of fish caught + Number of tagged fish in catch
=100 +24
= 124
So, the best estimate to find the number of fish in the pond is 124.
Hence, Option 'd' is correct.
The correct answer is option C, The vary from ecosystem to ecosystem
The factors which limitizes the growth of an ecosystem are called limiting factor. The four common limiting factors are food, water, shelter and space which is same for all organisms while there are some abiotic factors that limit ecosystem growth such as temperature, precipitation, sunlight, soil configuration, and soil nutrients which are also same. But some time there can be special factors which may limitise the ecosystem growth and thus option C is the apt answer
