| In-situ conservation | Ex-situ conservation |
| (1) In-situ conservation is a onsite conservation. | (1) Ex-situ conservation is done outside the habitat of plants and animals. |
| (2) Plant and animal species are conserved in their natural habitat for protecting endangered species. | (2) Plant and animal species are conserved in artificial or manmade place. |
| (3) It is done in natural environment. | (3) It is done in manmade environment. |
| (4) National parks, Sanctuaries, biosphere reserve, etc. are set up for in-situ conservation. | (4) Zoo, aquarium, seed banks are the examples of ex-situ conservation |

| (6) Captive breeding is not successful in all cases of in-situ conservation method. | (6) Captive breeding is successful and can help in increasing the number of endangered organisms. |
| Genetic diversity | Species diversity |
| (1) Genetic diversity is intraspecific diversity. | (1) Species diversity is interspecific diversity. |
| (2) Genetic diversity is due to number and types of genes and chromosomes present in different species. | (2) Species diversity is due to number of species of plants and animals that are present in a region. |
| (3) Genetic diversity includes variations in genes, alleles and chromosomes | (3) Species diversity includes species richness and species evenness. |
