An organism that can make its own food is called an "Auto-troph". They maybe of two types:
1) Photo-Autotroph (Get source by sunlight)
2) Chemo-Autotroph (Get source by chemicals i.e., CH₄, NH₃ etc.)
Hope this helps!
Wells, tube-wells, rivers, lakes, dams etc. Methods of management of water resources include rainwater harvesting, construction of bawris and khadins and water harvesting structures on the level terrain.
Answer:
The answer is "TRUE!"
Explanation:
Weight is a source of forceful motion that is generated by the pull of gravity. Gravity that is originated in the center of the earth, attracts smaller objects towards that center, in which the measurement of how strong that force really is, is weight.
Answer:
phototropism
Explanation:
The student was investigating phototropism.
The student wanted to know the response of the roots to light, that is why he exposed them to light.
Roots naturally exhibit two types of tropisms.
The first is gravitropism whereby they tend to grow downwards.
The second is hydrotropism whereby they grow towards the direction of water.
In the above experiment, no water was provided, the roots grew away from the light source but not specifically downwards.
