Let us look at some abiotic factors and their effect on seeds as they grow into young plants. Activity 2 Recall Activity 5 in Chapter 1 — we made sprouts from moong and chana seeds.

When required, check for the possible abiotic degradation of the test substance by determining the removal of DOC, oxygen uptake or carbon dioxide evolution in sterile controls containing no inoculum. Sterilize by filtration through a membrane (0.2-0.45 µm) or by the addition of a suitable

media.nationalgeographic.orgOcean Abiotic Factors, continued • Tides are the periodic short-term changes in the height of the ocean surface at a particular place. Tides are caused by the interaction of gravitational forces of the sun and moon and the rotation of the Earth. Most parts of the ocean experience two high tides and two low tides daily.

Green plants are called autotrophs, as they absorb water and nutrients from the soil, carbon dioxide from the air , and capture solar ener gy for this process.

An ecosystem and a habitat are similar because they both include the environment surrounding an organism. However, unlike an ecosystem, a habitat’s boundary depends on the particular organism whose habitat it is. A habitat may be a subset
Inherent Factors Affecting Soil pH
