Answer:
Human impact on the environment.
Explanation:
Human is the main responsible for the change in the environment. Human activities causes severe damage to the environment. The habitat of different species were destroyed by human for its own purpose. Large number of forest were eliminated for making land suitable for construction and living. Due to vehicles and industries, large amount of carbondioxide is emitted in the atmosphere which contribute in rising the temperature of the earth atmosphere. This global warming change the habitat of different organisms and these organism will die or migrate to other suitable places. Acid rain also occurs due to the emission of CO2, CO and SO2 from vehicles and industries. This acid rain causes adverse effect on the animals, plants and infrastructure or buildings.
C. producer, the corn creates its own 'food' with photosynthesis. It's easier to remember as a flow chart producer(typically plants)->primary consumer(mostly herbivores)->secondary consumer(predators and other meat eaters) and decomposers(usually fungus) eat basically everything.
Answer: By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
