Ecologists make models of habitats and ecosystems to study questions that would be impossible, impractical or unethical to answer by testing actual ecosystems. Instead, ecologists concoct complicated mathematical programs that should react in similar fashion to real ecosystems when faced with similar stimuli. According to an article in BioScience, models often produce surprising and unexpected results.Know More
For example, an ecologist may create a model that tries to determine how the energy flows through a small pond ecosystem. Accordingly, the scientist would have to design the model to account for all the various ways energy enters the ecosystem, such as the sun, creatures traveling to the water and plant matter sinking in the pond. Additionally, the ecologist would have to ensure the model accounts for all the ways energy leaves the ecosystem, such as when animals leave the pond.
Models are not perfect recreations of the natural world, and sometimes they produce results that are later demonstrated to be false. This causes many ecologists to tweak their models periodically in pursuit of a model that accurately reflects the real world. Because models are used so extensively in ecology, the National Career Services in the United Kingdom recommends that prospective ecologists have a working knowledge of computers.Learn more about Environmental Science
An ecological succession activity is a series of changes in the environment and ecosystems. It refers to the evolution of ecology, just like humans evolve. Although some habitats may remain the same, others evolve constantly.Full Answer >
It is important to protect the environment because man-made disruptions to ecosystems can cause extinction, because pollution creates dangers for both animals and people, and because mankind owes the natural world a moral obligation. Many of the dangers to the environment come from practices designed to make human life easier but actually threaten the long-term health and prosperity of humans.Full Answer >
Biodiversity is important in ecosystems because it prevents extinction of species, allows organisms to adapt to changes in the environment and provides a wide range of materials and foods for survival. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity.Full Answer >
Curbing global warming, improving the health of oceans and marine ecosystems, and protecting endangered wildlife are just a few of the issues affecting the field of ecology, as of 2015. Many issues pose a threat to natural environments and ecosystems. Issues being confronted by ecologists may include safeguarding natural ecosystems and protecting species diversity and populations.Full Answer >
