Why does ecosystem exist in fragile balance

Develop an appreciation for the complexities of the Lake Pontchartrain Basin's varied ecosystems, as well as an understanding of how biodiversity or a lack of affects the health of an ecosystem. Understand the various relationships and roles of organisms in a food chain and how these relationships can become unbalanced. Realize the important role each of us plays in preserving and maintaining the health and biodiversity of the ecosystems of the Lake Pontchartrain Basin.

List several threatened and endangered species in the Lake Pontchartrain Basin. Understand the status and roles of threatened, endangered and introduced species in the Lake Pontchartrain Basin. Interpersonal: Choose opposing sides to defend a current, relevant social and ecological issue.

Intrapersonal: Explain personal values regarding selected environmentalissues of the Lake Pontchartrain Basin. Objectives Ecosystems in Delicate Balance Healthy vs. Examples of living and non-living parts include plants, animals, soil chemistry, temperature, nutrient supply, etc. Ecosystems in their natural state are finely-tuned and well-balanced. Ecosystems support and depend upon a tremendous diversity of plants and animals. Large numbers of animals and plants in the ecosystem indicate higher levels of biodiversity and greater complexity.

Biodiversity Imagine the ecosystem as a tiny city, bustling with "people". This city has a tremendous number of important jobs which need to be carried out all day long, every day. Plants convert sunlight to energy; insects convert plant matter to energy; other animals eat insects and each other; decomposers, rippers and shredders tear everything down to make room and nutrients for new plants and animals All of these jobs need to be taken care of by someone The Sun provides energy to Producers green plants and algae, etc.

Producers provide energy to Primary Consumers herbivores, or organisms that eat only plants. Primary Consumers provide energy to Secondary Consumers carnivores, animals that eat herbivores, or omnivores, that eat both plants and animals.

Secondary Consumers provide energy to Tertiary Consumers carnivores and scavengers who occupy the tops of their respective food chains, like eagles or humans. Decomposers are microorganisms like bacteria and fungi which cause a breakdown of dead organic tissues plants and animals , releasing their stored nutrients for re-use.

Nutrients released by decomposers are re-used by producers, starting the cycle over. A certain amount of energy is lost in each stage of the food chain. This effectively limits the overall length of any given food chain. A stable ecosystem requires balance. Log in. See Answer.

Toggle navigation. Language English. Ecological Balance Karen Hill tribes living in balance with nature. Ecology is the science of the study of ecosystems. Ecological balance has been defined by various online dictionaries as "a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession.

This balance may be disturbed due to the introduction of new species, the sudden death of some species, natural hazards or man-made causes. In this field trip we will explore how human population and development affects the ecological balance.
