Competition negatively impacts both species as they compete for the same limited resources.

The fig tree provides a site for wasp egg-laying, while the wasp pollinates the fig tree, making it a mutualistic relationship.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Interactions - Mutualism and Amensalism
Symbiosis involves close and prolonged interactions between species, while competition is a struggle for limited resources without direct dependency.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Interactions - Parasitism and Commensalism
Barnacles benefit from attachment to a whale without harming or benefiting the whale, making it a commensal relationship.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Interactions - Parasitism and Commensalism
Parasitism benefits the parasite while harming the host by extracting nutrients or causing disease.

Chlorella, a green alga, commonly forms a symbiotic association with fungi to form lichens.

The organism is a lichen. Its algal phycobiont prepares food, while its fungal mycobiont provides shelter and absorbs water and mineral nutrients. Lichens do not grow in polluted areas and therefore indicate air pollution.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Viruses Viroids Prions and Lichens
The organism is a lichen. The algal phycobiont prepares food, while the fungal mycobiont provides shelter and absorbs water and mineral nutrients. Lichens do not grow in polluted areas and therefore indicate air pollution.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Viruses Viroids Prions and Lichens
In lichens, the algal phycobiont prepares food, while the fungal mycobiont provides shelter and absorbs water and mineral nutrients. Lichens do not grow in polluted areas and therefore serve as pollution indicators.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Viruses Viroids Prions and Lichens
The phycobiont is the autotrophic algal partner and prepares food. The mycobiont is the heterotrophic fungal partner; it provides shelter and absorbs mineral nutrients and water for the association.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Viruses Viroids Prions and Lichens
The association is a lichen. The algal phycobiont prepares food, while the fungal mycobiont provides shelter and absorbs water and minerals. Because lichens do not grow in polluted areas, they indicate air pollution.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Bacteria - Structure and Economic Importance
The organism is a lichen, a mutually beneficial association between an algal phycobiont and a fungal mycobiont. The alga prepares food, while the fungus provides shelter and absorbs water and minerals. Lichens do not grow in polluted areas and therefore act as pollution indicators.
