Which one of the following is the correct sequence of a food chain?a)A...

Pond ecosystem is a freshwater ecosystem on which living organisms rely for their survival and food. Ponds are shallow water bodies going about 12–15 feet deep. Due to enough light penetration, ponds can facilitate plant growth.
All ponds support a wide diversity of plant and animal life that unitedly forms food chains and food web. One of the food chains in pond ecosystems consists of Algae, Water fleas, Sticklback and Pike.
- Algae are a large group of simple organisms. They are photosynthetic like land plants.
- Water fleas are small crustaceans. They are found in fresh waters. They mostly eat small algae and microscopic plants.
- The stickleback is a fish with no scales, although some have bony armour plates. They feed on small crustaceans and fish larvae.
- Pike is a freshwater fish, it eats smaller fish, insects and amphibians such as newts or frogs.
- Hence the correct food chain sequence is Algae - Wateflea - Stickleback - Pike. Hence option (a) is the correct answer.
If farmers remove the pike from the top of food chain then there will initially population explosion of the stikle back. However, these will soon eat all the waterfleas and die of starvation, leaving the algae to grow unchecked and choke up the pond.If a food web has only a few links then the effect of removing one species on the remaining organisms can be severe but if a food web has many links, then removal of one species may not have such a drastic effect.
