Answer 1

Answer:

Ecology : study of environment( study of relation between living and non living and their effect on environment).

photosynthesis: a method by which autotrophs create their own food

carnivorous: organisms which feed on other living creatures(animals) which eat flesh.

herbivorous: consumers which feed on autotrophs, eat plant or plant products.

detritivore: which feed on detritus i.e. survive on dead and decaying matter

omnivore: animals which eat plant and plant based products and also eat flesh and egg

autotrophs: which create their own food .like plants.

heterotrophs: which can not create their own food . like animals

biomass: all the living , organic matter present on earth.

biogeochemical cycle : a cycle containing recycling of chemicals in environment with the help biotic components.

Explanation: these  definitions are self explanatory.

Answer 2

Answer:

These are principal terms we have already learned in Biology. We can recollect them as follows.

Explanation:

• Ecology is a branch of Life Sciences that studies the relationships and interlinking of the living and non-living things, and their necessities and effects on the environment.
• Photosynthesis is the natural phenomenon found in plants and some bacteria (autotrophs, to be precise) that use solar energy to convert some inorganic materials into organic sources of energy.
• Carnivores are biological living organisms that feed on other living organisms made of meat. They are heterotrophs, and can't synthesize food on their own.
• Herbivores are biological living organisms that feed on other living plants. They, too, like carnivores, are heterotrophs and can't synthesize their own food.
• Detritivores are biological living organisms that feed on detritus (dead and decaying organic matter). They, like herbivores and carnivores, are heterotrophs and can't synthesize their own food.
• Omnivores are biological living organisms that feed on both plants and animals, and thus, are heterotrophs, too.
• Autotrophs are biological living organisms that synthesize their own food from inorganic matter and solar energy.
• Heterotrophs are biological living organisms that depend on autotrophs or other heterotrophs for food, depending on their feeding habits.
• Biomass is the total sum of al the living and organic matter present on the Earth.
• The Biogeochemical cycle involves the cycling usage and synthesis of chemicals in the environment by different biotic components.
