The Alpine Biome What is a biome? Well‚ according to the Merriam Webster Dictionary‚ a biome is simply “a major ecological community type.” This is just a brief definition. In detail a biome is a large ecosystem that contains animals and plants that adapt in that certain type of environment. The climate and geography of the region determines the biome. The biosphere is anywhere on the Earth where life exists. It can range anywhere from the skies to the depths of the ocean where anglerfish and squids

Examples of abiotic factors are weather‚ water‚ shelter‚ humidity and examples of Biotic factors are predators‚ prey‚ parasites‚ pathogens etc. 5. What is the difference between the tolerance range and the optimum range for abiotic factors (Figure 7.1 may help)? Tolerance

Air and water pollution affect the biotic and abiotic environment on a global scale. All pollutants affect individuals in different ways‚ but mainly affect those with asthma or underlying respiratory conditions. Transportation and energy consumption are the biggest contributors to pollution and global warming. With world population on the rise‚ carbon dioxide in the atmosphere is also climbing a steep hill. CO2‚ a primary air pollutant‚ is the most major concern amongst environmental scientists‚

composed of many ecosystems‚ which are smaller communities of plants and animals and their habitats‚ the physical parts of their environment that affect them. Whereas‚ the boundaries of a biome are determined by climate‚ the boundaries of ecosystems are physical features‚ such as ridges or riverbanks‚ which separate one community from another. Any given place may have several different ecosystems that vary in size and complexity. A tropical island‚ for example‚ may have a rain forest ecosystem that covers

Water ecology‚ which studies on the interaction between of biotic and abiotic factors to the growth of organism in water‚ is too important in order to keep the ecosystem balance. In our study‚ we focused on how the fertilize (nitro‚ phosphorus) effects on the populations of water organisms. Euglena is the mixotrophic which could synthesis energy from photosynthesis

The benefit of a desert’s biodiversity is that each organism can help other organisms survive or‚ at the least‚ maintain. For instance‚ lizards eat insects and insects eat plants. So the lizards eating the insects protect the plants from any damage the insects may cause to the plants. As shown in the diagram below‚ three categories of a desert ecosystem are producers‚ consumers‚ and decomposers

levels: The levels of nourishment in a food chain. Food Web: Shows the network of feeding relationships between trophic levels within an ecosystem. Food Chain: Shows one path of energy flow through an ecosystem Hydrologic Cycle: The water cycle. Biogeochemical Cycle: The movement of particular chemical through the biological and geological parts of an ecosystem. Nitrogen Fixation: Process when certain types of bacteria convert gaseous nitrogen into ammonia. Biomass: A measure of the total dry

There are two things that make up an ecosystem‚ the areas physical features (abiotic factors) and living organisms (biotic factors). The organisms living together in an ecosystem are called a community. Sometimes things in one ecosystem are affected from another ecosystems‚ so ecosystems are not self contained. Ecological

Dissolved oxygen is a basic requirement for a healthy aquatic ecosystem. It is measured in parts per million‚ the higher the higher the DO concentration the better. Most fish species cannot survive in DO concentrations less than 4ppm. pH is represented on a scale from 0 to 14 with 7 being neutral‚ natural waters usually
