In time immemorial living things (the biotic factors) and non-living things have been interacting with one another for one reason‚ which is to survive. Both factors interact in one grandiose community where-in all forms of ecosystems‚ such as: desert‚ savanna‚ tundra‚ tropical rain-forest‚ and the like; are deem to be found and this community is our planet earth. As found in many textbooks and other science oriented reading materials‚ the earth is also considered as an ecosystem as well because

even leap from branch to branch to escape the situation. An example of a mutualism in a koala bear is the bacteria in the koalas stomach. This bacteria allows koala bears to get their food without dying from the poison in the leaves. An example of commensalism is the relationship between the koala bear and the eucalyptus tree. The koala bear uses the tree for shelter‚ and a place to hide from predators. Commensalism is present due to the koala bear benefitting from the tree and the eucalyptus

Name: Rodrigo Alba Date: May 22‚ Global Warming and how it is affecting the Arctic Tundra The Arctic tundra is a region in the Northern Hemisphere that encompasses areas such as Canada‚ Alaska and much of Siberia in Russia. The word tundra refers to a vast treeless plain and is thought to have been adopted from the Finnish word tunturia (Arctic). Tundras are characterized by permanently frozen ground cover known as permafrost. The Arctic tundra is characterized by low precipitation and

Mutualism is an example of when both members/participants benefit from the partnership. In the example given in the video a commensalism relationship may be a hole in a tree and an owl living in it. The owl benefits the

Basic Ecology Terms: Ecology- the study of how organisms interact with their environment Organism- a living thing that gets food‚ water‚ shelter‚ and other things it needs to live‚ grow‚ and reproduce from its environment Habitat- environment that provides needed things Biotic Factors- the living part of a habitat Abiotic Factors- the non-living part of a habitat (soil‚ oxygen‚ water‚ sunlight‚ temperature) Species- a group of organisms that can mate with each other and produce offspring that

microbes as a “commensal” microbiome. Commensalism is defined as non-harmful coexistence between two organisms‚ where food or some other benefit is received by one party‚ without causing damage to the other. To their benefit‚ bacteria obtain energy to ensure their own survival‚ and to ours‚ they help us break down fats and carbohydrates‚ produce vitamins and hormones‚ train our immunity‚ and protect us from a hegemony of pathogenic microbes. Commensalism or mutualism? Both can be used to describe the

The Savanna A Savanna is a grassland ecosystem characterized by being sufficiently spaced so that the canopy does not close. Savannas are also characterized by seasonal water availability‚ with the majority of rainfall confined to one season. Savannas are associated with several types of biomes. Savannas are frequently in a traditional zone between forest and desert or grassland. The Savanna covers approximately 20% of the earth’s area. The Savannas is a wet and dry climate‚tropical savanna monthly
