Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.

Answer:
1) Stirring and pulverizing the soil before seeds are planted or removed as well as to loosen the soil in order to allow enough air into the soil.
2) Vitamin A, zinc supplementation and exclusive breastfeeding
3)Manure from horses, cows or cattle
4) Mechanical
Explanation:
A cultivator is a farm implement used for stirring and pulverizing the soil before seeds are planted or removed as well as to loosen the soil in order to allow enough air into the soil. This enables the crop to grow quicker. It is driven by a tractor and does more work than the harrow which is not tractor driven.
Nutrition-specific intervention is a programme by UNICEF to talk undernutrition in foetus as well as growing children. The nutrients specified are exclusive breastfeeding, vitamin A and zinc supplementation.
Manure is referred to as major component used to aid crop growth. It contains essential nutrients which are required by crops for growth and good health. Manure is natural and can be gotten from animal dung.
Seed drills are sowing machines used to sow seeds accurately at the precise depth and distance measured. It does an extra work of covering the soil as well as protecting the seeds from birds. Due to the fact that it is a machine, it saves time and labour as well as money.
The correct answer is by composition and texture. Composition is that minerals that the rock are made of. Texture refers to the grain size of the different components of that rock. Texture has to do with sizes of mineral grains and other constituents in a rock and how the sizes and shapes relate to each other.
