All living organisms need nitrogen to synthesize proteins. Proteins form the structure of the organism and provide life-sustaining functions, including development, growth, and reproduction. The nitrogen cycle is a process by which nitrogen is transforming its chemical compound forms. This transformation can be performed by…
What is ecological balance? Ecological equilibrium is a term used to describe the equilibrium between living organisms such as humans, plants and animals as well as their environment. Photosynthesis taking place in the ecosystem contributes to building a good environment that stabilizes the coexistence of…
Just like humans, plants require female and male organs to produce seeds that can then grow into new plants. The difference here is that plants have both male and female genitalia on the same body. Pollination is the process that allows plants to reproduce. In…
How does the ecosystem work? Has your car ever broken down on the road? Usually, a car breaks down because one part of the vehicle is damaged. There are many parts that make a car work. A spark ignites the fuel, the wheels move the…
You may have pulled a tree off the ground with the trunk and found a mess of roots below, but do you know how roots and stems help the tree live? Structure and function of tree roots Tree roots Tree roots are a vegetative organ…
Definition Ecological niche (ecological nest) is a collection of all ecological limits of an organism. An ecological niche is the role and position of a species in its habitat; how it meets its food and shelter needs, how it survives and how it reproduces. The…
What is a predator? In the wild, predators are animals that hunt, kill and eat other animals. The food that a predator hunts is called its prey. Types of predator The big predators Predators come in all shapes and sizes. They all have special adaptive…
Definition Habitats are the living environments of one or many plants and animals. Most of all the places on the earth which include the hottest deserts to the coldest places are habitats of some plants or animals. Most of the habitats include an animal or plant…
Definition of Ecological Succession Ecological succession is the process of sequential change of biomes through different stages, from the initial (or pioneering) state, to being replaced successively through transitional periods by community types. Subsequent and final often leads to a relatively stable community or steady…
Biological interactions are the impacts and relationships among organisms in an ecological community. In the natural world, no living thing exists in absolute isolation and therefore all living things must interact with the environment and interact with other organisms. The interaction of an organism with…
