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.
Two density-dependent limiting factors include competition and disease. Both of these factors rely on the size and density of a population because it creates conflict over limited resources (competition) and the more dense a population is, the easier it is for pathogens to spread and infect many individuals (disease).f the population density in the ecosystem were to increase, competition over these cacti would increase, making this a density-dependent limiting factor. Only a certain density of Cactus Wren can be supported in an ecosystem. Another example of a density-dependent limiting factor is disease.
