Being eco-friendly includes recycling, but there are other ways to guard the planet's health. In recent years, terms like going green and eco-friendly have become buzz words on talk shows, commercials and product packaging. The term eco-friendly has been used for so many different products and practices, its meaning is in danger of being lost.
The abiotic factors of temperate grasslands include low rainfall, moderate humidity, large temperature differences between winter and summer, seasonal fires and rich nutrients in the soil's upper layers. Temperate zones are regions between the tropics and poles, and abiotic factors are an ecosystem's nonliving parts.
A limiting factor is a factor that restricts the size of a population from reaching its full potential. The amount of food & water in a habitat is an example of a limiting factor. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. An example of a limiting factor is sunlight in the rainforest, where growth is limited to all plants in the understory unless more light becomes available.
