Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Greater biodiversity implies greater health. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas polar regions support fewer species.
Rapid environmental changes typically cause extinctions. One estimate is that less than 1% of the species that have existed on Earth are extant.
Making a model for biodiversity is a common project assigned in schools during science lessons to teach the pupils more about biodiversity. It is not just students who study biodiversity and create models, scientists have been creating models of biodiversity for years. Biodiversity must be examined and closely analysed in an attempt to lessen the impact of shrinking ecosystems. The loss of biodiversity can have a huge effect on the entire planet, as one ecosystem inevitably affects the next and the loss of one has a huge effect. All of our plants, animals and environments are working together to create biodiversity. Models that are created, experimented upon and analysed, are then used to make predictions and interpretations for our future. There are often debates surrounding the experiments as different results can be interpreted in different ways by many different people.
When choosing your working model of biodiversity, focus on something you enjoy or an area of biodiversity that you are particularly interested in. A genuine interest and passion will always lead to better results as you will remain enthusiastic throughout the project. Think of a mini environment that you can closely observe and analyse any changes that take place. Ensure that plants and animlas are included to show how one can affect another. Popular topics include analysing the biodiversity of a fish tank. This is relatively inexpensive and a simply project to undertake. Use a fish tank or large bowl, add some pebbles and plants and some goldfish from your local pet store. Make sure you take photos to keep track of the progress of the biodiversity that is growing in your tank as it may happen so slowly that you barely realise a change is occurring.
