Answer:
Science has a central role in shaping what count as environmental problems. This has been evident most recently in the success of planetary science and environmental activism in stimulating awareness and discussion of global environmental problems. We advance three propositions about the special relationship between environmental science and politics: (1) in the formulation of science, not just in its application, certain courses of action are facilitated over others; (2) in global environmental discourse, moral and technocratic views of social action have been privileged; and (3) global environmental change, as science and movement ideology, is vulnerable to deconstructive pressures. These stem from different nations and differentiated social groups within nations having different interests in causing and alleviating environmental problems. We develop these propositions through a reconstruction of The Limits to Growth study of the early 1970s, make extensions to current studies of the human/social impacts of climate change, and review current sources of opposition to global and political formulations of environmental issues.
Answer: 
Explanation: Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.
The balanced chemical equation for photosynthesis is written as :

Answer:
Your answer is most probably A). B) implies that nuts are the only thing for birds to eat in a rainforest, which doesn't make sense, C) implies that the insects would need a widely-varied diet to survive, but again there's an abundance of things that a hungry bug can eat, so they don't need a wide dietary coverage, D) suggests that there may be droughts in the area for which the plant may need to be prepared, but in the RAINforest droughts are uncommon.
They obtain energy by consuming other organisms.
It’s D, other answers don’t make sense
