Individual Organisms needing Resources from their Environment

Individual Organisms needing Resources from their Environment

  • Individual organisms require resources from their environment to survive, grow, and reproduce.

  • These resources include basic needs such as water, air, light, and nutrients.

  • As a principle, all living organisms need energy. This energy is primarily derived from the sun in a process called photosynthesis.

  • This energy is then passed along to other organisms through the food chain.

  • Organisms also need material resources for growth. For example, plants use carbon dioxide, water, and certain minerals from the soil for their growth.

  • These requirements are not constant and can change based on the specific stage of life or the current environmental conditions.

  • Most organisms have the ability to adapt to changing environmental conditions in order to maximise their use of resources.

  • Competition occurs when the resources in a habitat are limited. Organisms compete with each other for resources such as food, territory, mates, and more.

  • Organisms also work symbiotically with each other to make the best use of available resources. Mutualism is an example of such a symbiotic relationship.

  • All organisms produce waste, which they must manage or get rid of so that it doesn’t build up and become toxic. Many waste products are harmful to the organism, so they have evolved ways to excrete wastes.

  • Understanding these interactions between organisms and their environments is crucial to maintaining and protecting biodiversity. Biodiversity is the variety of living organisms found in a particular habitat or ecosystem.

  • Environmental changes can potentially disrupt these interactions, leading to a possible loss in biodiversity. Conservation is therefore necessary to preserve a balanced environment.
