An ecosystem is all the living things and nonliving things in a place that interact together, such as an oasis, a meadow (rawdah), or the sea. In this lesson you distinguish living factors from nonliving ones, and learn about populations, communities, and habitats.
💡 Tip: Remember the order from smallest to largest: an individual, then a population of one species, then a community of many species, then an ecosystem, which adds the nonliving factors.
Ghada explains the lesson and answers your questions about it. Log in to get started.
A population is members of one species in one area, such as 40 gazelles in a reserve. A community is all the populations living together, such as the gazelles, rabbits, birds, and grasses in a meadow.
Water, sunlight, air, soil, rocks, and temperature. They are not living things, but they affect the lives of plants and animals.
