Micro-evolution refers to the alteration in a gene pool of the population over time, resulting in small changes of an organism in the same species. On the other hand, Macro-evolution refers to the alteration in organisms, and these changes gradually give rise to completely new species, which is different from their ancestors. The genetic change in the scale of descent over time or heritable change in a population of an organism; brought up by the process like genetic drift, mutations, gene … [Read more...]

The biological process, where ammonium gets converted into nitrate is called as nitrification. Further, when this nitrate is converted or reduced into nitrogen gas, it is called as denitrification. These steps involve various microorganisms, and it is important biologically as well as economically. Both the steps are a significant part of the nitrogen cycle, which is one of the most important cycles for our atmosphere. Around 78% of the atmosphere contains nitrogen, which is even essential … [Read more...]

Biodegradable substances are those that degrades or break down naturally. Non-biodegradable substances are those that do not degrade easily. These terms itself defines the ability of the substances which are degradable or not. Materials like plants, animals, their waste, paper, fruits, flowers, vegetables fall under biodegradable substances, on the other hand, rubber, plastic, chemicals, paint plastic falls under the category of the non-biodegradable items. The environment in which we live is … [Read more...]

Primary Succession can be defined as the process of growth in an area that was previously uninhabited, barren, unoccupied and there was no initial vegetation. On the other hand, Secondary Succession can be defined as the growth of the community in such area which was previously occupied, inhabited and that has primary vegetation but got disturbed or damaged due to some external or internal factors. The example of Primary Succession is the newly formed bare rock, desert, ponds, etc., while the … [Read more...]

The primary difference between both is that abiotic factors include those components of the ecosystem which are non-living part of any habitat. On the other hand, biotic factors include living components of the ecosystem. The examples of the abiotic factors are sunlight, the wind, clouds, water, rocks, energy, temperature, soil, etc. while the examples of biotic factors are plants and trees, animals, microorganisms such as fungi, bacteria, algae. The ecosystem provides the major platform … [Read more...]

The basic difference between phytoplankton and zooplankton is that the word 'phyto' is used for the small plants like diatoms and algae and word 'zoo' is used for the small animals like tiny fish, crustaceans, which are the weak swimmers and just move along the currents. The word "plankton" refers to the smallest aquatic plants or animals that float and drift in the limnetic zone of water bodies. Planktons are divided into two categories where one is called as permanent plankton and the other … [Read more...]

Habitat is a set of the place of environmental conditions in which particular organism lives and adapt the situation accordingly. A niche is nothing but an idea or role played by organisms that how they can live in an environment including their diet, shelter, etc. Mainly niche is concerned with the factor of gaining energy by organisms and supplying it to other, in the ecosystem. A habitat defines the interaction of organisms with the other factors, which can be living or non-living, while … [Read more...]

The basic difference between Ecosystem and Community is that Ecosystem consists of various communities which include living as well as non-living components interacting with each other, whereas interaction of different individuals of populations of different species living in a particular geographical area is called Community. The community consists of only biotic factors only. Our Earth is the only planet comprising life from the microscopic organisms to the large animal.To understand life … [Read more...]
