Answer:
Linear and non_ linear scales
Explanation:
Answer:
(Ca2 +, Mg2 +, Na+, and K+) and four major anions ( , , SO 4 2 - , and Cl-) with ionic forms of N, P, Fe, and other trace elements at lower concentrations (Livingstone 1963, Meybeck 1979) (Table 4.7).
B. lithium (Li)
C. neon (Ne)
D. radon (Rn)
Answer: Option (A) is the correct answer.
Explanation:
It is known that atomic size of atoms decreases on moving from left to right in a period of the periodic table. Whereas atomic size increases on moving from top to bottom in a group.
Lithium and cesium are both alkali metals. On the other hand, both neon and radon are noble gases.
Both cesium and radon belongs to sixth period. Cesium being at the extreme left side is larger in size than radon which is at the extreme right side of periodic table. Therefore, atomic radius of cesium will be larger than atomic radius of radon.
Whereas both lithium and neon belongs to second period. Lithium being at the top left side of periodic table has larger atomic radius than neon which is at the top right side.
Thus, we can conclude that out of the given options cesium has the largest atomic radius.
B. magnesium and oxygen
C. magnesium and magnesium
B.) Evaporating
C.) Condensation
D.) Melting
Decomposers
Primary consumers
Secondary producers
Answer: Primary producers
A food chain is a linear series of transfer of food and energy when one organism is consumed by the other organism in an ecosystem. The energy is distributed among different tropic levels of the food chains.
Phytoplankton is a class of unicellular simple, autotrophic organisms which are found in water of ocean, lakes and or any other freshwater body. These includes dinoflagellates, diatoms, cynobacteria, green algae and others. These organisms are abundantly present in the ecosystem in the lower most trophic level. They are called as primary producers because they are consumed by other organisms such as zooplanktons, fishes and large sea mammals.
