Pyramid of Numbers – Definition, Types, Importance, Examples

Pyramid of Numbers - Definition, Types, Importance, Examples

What is Pyramid of Number? The Pyramid of Numbers is a graphical representation used in ecology to illustrate the distribution of various species in different trophic levels of a food chain. This pyramid provides a quantitative analysis, showing the number of individual organisms present at each trophic level. Unlike other ecological pyramids which might consider … Read more

Microbial interaction – Definition, Types, Characteristics, Examples

Microbial interaction - Definition, Types, Characteristics, Examples

Microbial interaction is a biological interaction in which the effect of microorganisms on other biotic components of an ecosystem can be investigated. Microbiology is the study of microorganisms, and microbial ecology is the study of microbial interactions within an ecosystem. Positive and negative microbial interactions are possible, and microbes can affect (positively or negatively) other … Read more

Carbon Fixation – Process, Pathways, Importance

Carbon Fixation - Process, Pathways, ImportanceCarbon Fixation - Process, Pathways, Importance

What is Carbon Fixation? Carbon Fixation Definition Carbon fixation is a biological process where atmospheric carbon dioxide (CO2) is converted into organic compounds, primarily by plants, algae, and certain bacteria. This process is a key component of photosynthesis, enabling the incorporation of inorganic carbon from the atmosphere into organic molecules like carbohydrates, thereby playing a … Read more

Primary Consumers – Definition, Importance, Examples

Primary Consumers - Definition, Importance, Examples

Primary consumers are fundamental components of ecological food chains, holding a critical position as the link between producers and higher trophic levels. In essence, they are organisms that feed directly on primary producers, typically plants or algae, which are capable of photosynthesis. Occupying the second trophic level, primary consumers are mostly herbivores, although some omnivorous … Read more

Secondary Consumers – Definition, Types, Functions, Examples

Secondary Consumers - Definition, Types, Functions, Examples

What are Secondary Consumers? Definition of Secondary Consumers Secondary consumers are organisms that primarily feed on primary consumers, which are herbivores, in a food chain. They occupy the third trophic level and can be either carnivores, who eat only other animals, or omnivores, who consume both animal and plant matter. Their role is vital in … Read more

Soil Biology – Definition, Types, Proterties, Importance

Soil Biology - Definition, Types, Proterties, Importance

What is Soil Biology? What is Soil? Components of Soil The components of soil exhibit variations in their ratios across different locations due to various soil-forming factors, climate, topology, the presence of organisms, human influences, and the duration of their interaction. These components can be broadly categorized into four main groups: The relative proportions and … Read more

Eutrophication – Definition, Causes, Types, and Effects

Eutrophication - Definition, Causes, Types, and Effects

What is Eutrophication? Definition of Eutrophication Eutrophication is the process in which a water body becomes overly enriched with nutrients, leading to the excessive growth of algae and plankton. This often results in the deterioration of water quality, depletion of oxygen, and ecological imbalances in the affected ecosystem. Causes of Eutrophication – What causes eutrophication? … Read more

Nitrogen Cycle – Definition, Steps, Importance, Examples

Nitrogen Cycle - Definition, Steps, Importance, Examples

What is Nitrogen Cycle? Nitrogen Cycle Definition The nitrogen cycle is a biogeochemical process that transforms atmospheric nitrogen into usable forms for living organisms and then returns it to the atmosphere through a series of biological and chemical reactions. Stages of Nitrogen Cycle Nitrogen fixation, nitrification, assimilation, ammonification, and denitrification are the steps in the … Read more
