Question

List 3 ways you, personally, can reduce your carbon footprint and explain how each reduces it.

What events are involved in the evolution of a new species?

Why is an ecosystem-based on a food web more stable than one based on a food chain?

answer all due in hour please typing please

Answer 1

Ans 1- 3 ways to reduce carbon footprint :-

1. Use of 3'R - reduce, reuse and recycle.

2. Use bicycle instead of car, protecting fuel will help in reducing the carbon footprint.

3. Use more of natural resources like sunlight, solar panels instead of electricity will help in reducing carbon footprint.

Ans 2- steps involved in evolution of new species are :-

Variation - natural selection - increase in progeny --> Evolution

Like this cycle goes on, variation is very important for evolution of new species, after variation, due to natural selection, one of the variation is selected that's imparts a advantage to the individual, individual grow in number and that change is passed on to its offspring.

Ans 3- it is because food web is more stable, it has more number of organisim, so even if one of the organisim gets removed it will be balanced by some other organsim. But in food chain, if one of the organisim is removed, whole food chain is disturbed.

Hope it helps you.
