Answer: Option A. -> The species which occur abundantly in the ecotone
The organisms which occur primarily or most abundantly in the ecotone are known as edge species.

Answer: Option D. -> Extinct
The dodo (Raphus cucullatus) is an extinct flightless bird that was endemic to the island of Mauritius, east of Madagascar in the Indian Ocean. The dodo's closest genetic relative was the also-extinct Rodrigues solitaire, the two forming the subfamily Raphinae of the family of pigeons and doves.

Answer: Option D. -> All of these
The extent of damage or danger posed to the environment depends upon the radioactive material concentration, the energy emitted by the radiation, proximity of the radioactive materials to those exposes, and the radiation type.

Answer: Option C. -> Reciprocal relationship between living and non living components
Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them.

Answer: Option A. -> Photosynthesis
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.

Answer: Option B. -> The wavelength of red light is longer.
Red light has a slightly longer wavelength than blue light. Red light (at one end of the visible spectrum) has a longer wavelength than blue light.

Answer: Option A. -> Oxidation
Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas and heat.

Answer: Option B. -> Reduce, Reuse, Recycle
The 3 R principle in waste management involves
Reduce, Reuse and Recycle.

Reduce, Reuse and Recycle.
Answer: Option D. -> Dew point temperature
Dew point is a good indicator of the air's actual water vapour content, unlike relative humidity, which takes the air's temperature into account. High dew point indicates high water vapour content; low dew point indicates low water vapour content.

Answer: Option A. -> Increase
If the sun suddenly began emitting more energy, the earth's radiative equilibrium temperature would increase.
