The key difference between competitive exclusion and resource partitioning is that competitive exclusion is a principle that says two species competing for identical resources can’t coexist, while resource partitioning is the division of limited resources by species to avoid interspecies competition in an ecological niche. There are different types of organisms living in one niche. […]
Difference Between Ocean Acidification and Global Warming
The key difference between ocean acidification and global warming is that ocean acidification is the worldwide reduction in the pH of seawater due to oceans absorbing huge amounts of carbon dioxide from the atmosphere while global warming is the long term gradual increase in the average temperature of the Earth’s atmosphere. Ocean acidification and global […]
Difference Between Activated Sludge and Trickling Filter
The key difference between activated sludge and trickling filter is that activated sludge is a suspended culture system in which biomass is mixed with the sewage while trickling filter is an attached culture system in which biomass is grown on media and the sewage is passed over its surface. Wastewater treatment is a critical process […]
Difference Between Bioaugmentation and Biostimulation
The key difference between bioaugmentation and biostimulation is that bioaugmentation is the addition of specific cultured microorganisms into contaminated soil or groundwater for the purpose of biodegradation of contaminants. Meanwhile, biostimulation is the modification of the environment by adding nutrients, electron donors and electron acceptors to stimulate existing microorganisms, especially bacteria that are capable of […]
Difference Between Terrestrial and Aquatic Biomes
The key difference between terrestrial and aquatic biomes is that terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes. Biomes are large ecological areas found on the Earth’s surface. In fact, they are specific geographical areas, but their boundaries are not sharply defined. Hence, there are transition zones between […]
Difference Between Carbon Cycle and Phosphorus Cycle
The key difference between carbon cycle and phosphorus cycle is that the carbon cycle is the biogeochemical cycle that describes the movement of carbon through the lithosphere, hydrosphere, biosphere, and atmosphere. Meanwhile, the phosphorus cycle describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Carbon, nitrogen and phosphorus are three major elements that […]
Difference Between Keystone Species and Foundation Species
The key difference between keystone species and foundation species is that keystone species are the species that have a greater effect on all the other species in an ecosystem while foundation species are the species that play a major role in creating and maintaining a habitat for other species. There are several categories of organisms […]
Difference Between Eutrophication and Algal Bloom
The key difference between eutrophication and algal bloom is that eutrophication is a process by which excessive growth of algae occurs due to release of nutrients, including nitrates and phosphates, into water bodies in larger quantities, while the algal bloom is the mass of phytoplankton rapidly grown in the water body as a result of […]
Difference Between Photic and Aphotic Zone
The key difference between photic and aphotic zone is that the photic zone is the portion of the ocean that receives sunlight while the aphotic zone is the portion of the ocean that does not receive sunlight. The ocean is the largest aquatic biome that can be categorized into different zones. Photic zone and aphotic zone […]
Difference Between Lichen and Mycorrhizae
The key difference between lichen and mycorrhizae is that lichen is a mutualistic association that exists between an algae/cyanobacterium and a fungus, while mycorrhiza is a type of mutualistic association occurring between roots of a higher plant and a fungus. Mutualism is one of the three types of symbiosis that occurs between two different species […]
