Answer:
Neither A nor B is correct
Explanation:
Hydrologic cycle is the sequence of different conditions through which the water passes from oceans to clouds, precipitates as rains, comes to the rivers and finally reaches the ocean.
This first statement in the question said that water will end up in the river which is not true because water from the river ultimately ends in the oceans because all the rivers terminate in the oceans finally.
The second statement is also wrong because when water from one ocean vaporizes and becomes cloud, it can travel large distances as clouds in the effect of wind and thus may get precipitated in the form of rain in some other part of the world. So, it is not necessary that the water will end up in the same ocean.
Clown fish and sea anemones.
Answer:
The advantage of this is that there is a larger surface area exposed, more time available and shorter difference for exchange of oxygen.
Explanation:
Solar planet in an undiscovered solar planet. With no other living organisms at its surroundings.
Answer:
he organisms that can fix energy from inorganic sources into organic molecules are called autotrophs. Organisms that cannot make their food from inorganic sources but depend on energy rich organic molecules synthesized by autotrophs for their energy needs are called heterotrophs.
The only source of energy for all the ecosystems of the earth is the sun. Light falling on the plants is trapped by the producers or autotrophs in the presence of chlorophyll and is used in synthesizing the organic food called glucose by the process of photosynthesis. By photosynthesis radiant energy of sunlight is transformed into potential energy of food. A part of this energy is trapped by the producers while the rest of the energy is dissipated. The remaining part of energy which is used in the synthesis of plant biomass is called photosynthate which is then available to the next trophic level in the food chain that is the consumers or heterotrophs. In an ecosystem there is a unidirectional flow of energy.
