Difference Between Abiotic and Biotic Factors (with Comparison Chart) - Bio Differences

relationship between biotic and abiotic environment

Thus, these biotic and abiotic components are linked to each other through nutrient is a significant difference in access to water as well as humidity between. The primary difference between both is that abiotic factors include those On the other hand biotic factors in include living components of the. Our results demonstrate a strong link between traits and the abiotic environment, biotic interactions and biogeochemical ecosystem processes (KiLi)". .. Relationships between the abiotic environment and plant traits and.

Collection of plant functional traits and data on animal taxa took place on 60 plots, each of 0. Plots were distributed equally among vegetation types, five plots belonging to each type. Undisturbed plots at low elevations around m a.

At m, coffee plantations and agroforestry systems harbored mostly dicotyledonous weeds. Grasslands were dominated by several taxa of Poaceae. Woody life forms accounted for the largest part of plant biomass from middle to upper elevations, with a transition from rainforest to cloud forest characterized by small trees and high lichen abundance at around m. Alpine vegetation occurred up to m and was mainly composed of shrubs, perennial herbs, and grasses.

Mean temperature was derived from several years of continuous measurements with automatic data loggers covering the time period of our data collection [ 42 ]. Annual precipitation data was derived from the Kilimanjaro rainfall model [ 43 ].

Disturbance was calculated as a composite metric including the effects of land use at local and landscape scales [ 44 ], S1 File. Abundance was defined as percent cover determined from vegetation surveys. Cover was estimated for each stratum depending on the vegetation structure of the plot. Plant functional traits were chosen to indicate vegetative growth, persistence, and reproductive characteristics.

Fifteen individuals per species were sampled from different plots within the elevational distribution range for specific leaf area SLAleaf dry matter content LDMCstem specific density SSDleaf nitrogen content leaf Nmassleaf phosphorus content leaf Pmassfruiting frequency, fruit number, and fruit size.

Additionally, the total plant biomass per plot was calculated with allometric equations using complete tree and undergrowth inventories details in [ 45 ].

Sampling and processing of plant material followed Kleyer et al. Percentage cover values from vegetation surveys were used to calculate community-weighted mean trait values for each plot CWM, [ 47 ]. The traits used are related to the worldwide leaf economics spectrum [ 3248 ], reflecting a gradient from plants with fast resource use and nutrient turnover to those with slow and persistent growth. The former are characterized by soft tissues with high nitrogen content and are generally preferred by herbivores, due to their easier digestion and higher nutritional value [ 32 ].

All data were collected on the same plots within a common time frame to avoid confounding effects of spatial and temporal variability. To quantify nectar and fruit availability on the plots, pollination and dispersal syndromes were extracted from the Flora of Tropical East Africa [ 49 ]. The sequence of transfer of energy from plants to herbivores and to carnivores forms a food chain. In an ecosystem there is continuous exchange of energy and carbon with the environment; mineral nutrients are cycled between plants, animals, microbes and soil.

Most of the nitrogen enters the system through biological nitrogen fixation. Nitrogen fixing bacteria are present freely in the soil or in symbiosis with plants. When these plants tissues are consumed the nitrogen in the tissues is available to the animals and microbes. Deposition from the microorganisms releases nitrogen from dead organic matter into the soil. Hence, abiotic and biotic components interact and work together in an environment that is best for all living organisms.

There are diverse factors of ecosystem but each factor plays its own role in the maintenance of the ecosystem. A biotic factor is any living component that affects another organismincluding animal s that consume the organism in question, and the living food that the organism consumes. Biotic factors include human influence. Biotic components are contrasted to abiotic component s, which are non-living components of an organism's environment, such as temperature, light, moisture, air currents, etc.

Biotic components usually include: Abiotic component In biologyabiotic components are non-living chemical and physical factors in the environment. Abiotic phenomena underlie all of biology. Abiotic factors, while generally downplayed, can have enormous impact on evolution.

Interaction between Biotic and Abiotic Components

Biotic factors are broken into three main categories: Autotrophs are defined as being living things that can self-feed. Plants and algae fall into this category because they can feed themselves. Of course, they need the area around them to help with sunlight, water and nutrients, but then they do the work to make their own food through either photosynthesis or chemosynthesis. Sciencing Video Vault Heterotrophs consume the forest ecosystem around them.

The final category, detritivores, are the decomposers. They are like the cleanup crew to both of the other categories because they eat dead things.

Many insects and worms fall into this category. What Is an Abiotic Factor?
