What is symbiosis ? Explain with example.?

Question

Answer

The condition in which two different organism live together and help each other to survive called symbiosis.

Answer

When some organisms live together and share shelter and nutrients  this is called symbiotic relationship or symbiosis and (such plant are called symbiotic plants ).For example lichen  a chlorophyll containing partner which is an alga  and a fungus live together.

Answer

The living together of two different species of plants as if they are parts of the same plant and help each other in obtaining food is called symbiosis (and such plants are known as symbiotic plants )this type of nutrition involving symbiosis occurs in plant called licheñ

Answer

SYMBIOSIS IS A RELATIONSHIP BETWEEN TWO ORGANISMS TO BENEFIT EACH OTHER.EXAMPLE-.LICHENS- THEY ARE THE COLONY OF FUNGI AND ALGAE.

Answer

A relationship in organisms in a such a way that they benefit each other in some way is known as symbiosis. EX- In lichens chlorophyll containing a partner of algae and fungi live together. Fungus give shelter, water and minerals and in return algae gives the food made by photosynthesis.

Answer

Symbiosis: A Mutual Relationship

Symbiosis is a biological term that refers to the close and long-term interaction between two or more different species. It involves a mutually beneficial relationship where both organisms benefit from each other's presence. This interaction can occur between individuals of the same species (intraspecific) or different species (interspecific). Symbiotic relationships play a crucial role in maintaining the ecological balance and stability of ecosystems.

Types of Symbiotic Relationships:

There are three main types of symbiotic relationships:

1. Mutualism: In mutualistic relationships, both species involved derive benefits from the association. It is a 'win-win' situation where both organisms rely on each other for survival and reproduction. Examples include:

- Pollination: Bees and flowers have a mutualistic relationship. Bees obtain nectar as a food source, while they inadvertently transfer pollen from one flower to another, aiding in the flower's reproduction.
- Nitrogen fixation: Leguminous plants have nodules on their roots that house nitrogen-fixing bacteria. The bacteria convert atmospheric nitrogen into a usable form for the plants, while the plants provide the bacteria with nutrients and shelter.

2. Commensalism: Commensalistic relationships occur when one organism benefits, while the other is neither harmed nor benefited. It is a 'win-neutral' situation. Examples include:

- Remoras and sharks: Remoras, a type of fish, attach themselves to sharks using a modified dorsal fin. They feed on scraps of food left by the shark, gaining protection and a source of food, while the shark is unaffected by their presence.
- Epiphytes and trees: Epiphytic plants grow on the branches of trees, utilizing them for support and access to sunlight. The trees are unharmed, but the epiphytes benefit from the elevated position.

3. Parasitism: Parasitic relationships involve one organism (the parasite) benefiting at the expense of the other organism (the host). The parasite derives nourishment and shelter from the host, often causing harm or disease. Examples include:

- Fleas and dogs: Fleas feed on the blood of dogs, causing irritation and discomfort. The fleas benefit from the dog's blood, while the dog suffers from the infestation.
- Tapeworms and humans: Tapeworms live in the intestines of humans, absorbing nutrients from the host's food. They harm the host's health and can lead to various complications.

Conclusion:

Symbiotic relationships are fascinating examples of how different species depend on each other for survival and success. They showcase the interconnectedness and interdependence of organisms in ecosystems. Understanding and studying symbiosis can provide valuable insights into the complex web of life on our planet.
