b. The ecosystem-size hypothesis
Explanation:
In this chapter, the ecosystem-size hypothesis is discussed. The ecosystem-size hypothesis is based on the relationship between ecosystem size and diversity of species, habitat availability and habitat heterogeneity. There will be increase occur in the food-chain length if the size of the ecosystem increases. The big size of ecosystem provides more space for living, more food to animals and other basic needs which the organisms needed for survival and growth.
Hornblende and other amphiboles have double chain silicate structures.
Tetrahedron (SiO4)^4- is the fundamental building block of all the silicate minerals. Silicate minerals comprising chains are known as inosilicates. In single chains, the ratio of silicon to oxygen is 1: 3, while it is 4: 11 in the case of double chains.
The double-chain silicates take place when tetrahedral produce a double chain by sharing two or three oxygen atoms each.
