A Ecologyis one of the most demanded subjects in National High School Examination tests (And either). This is because the topics covered by Ecology, in many cases, address everyday issues, involving current issues.
Climate change, ecological interactions among living beings, pollution, food chains and webs, as well as basic concepts such as ecological niche and habitat are some of the topics covered by the tests.

Ecology is certainly one of the subjects with the greatest possibility of interdisciplinarity in the tests of the Enem, because ecological issues may be related to Biology, Chemistry, History, Physics, etc.
Check below the ecology concepts, one of the subjects that fall most in the enem.
Basic concepts of ecology
Ecological concepts are often discussed because they are the basis for understanding other processes, so it is important to know some basic concepts such as:
- Habitat and ecological niche
- Biotic and abiotic factors
- Food chain
- food web
- Community
- ecosystems
- Biosphere
- Biogeochemical cycles
Environmental problems
The tests of Natural Sciences in Enem always bring questions addressing environmental problems that may or may not involve other areas of knowledge.
Issues such as dumping substances in aquatic environments, dam break, burned, logging and acid rain may be present in Ecology issues.
Environmental preservation
A environmental preservationis an important topic for the Enem exams, as it addresses issues related to our daily lives, such as reducing consumption, garbage recycling, use of biodegradable products, etc.
These themes are usually addressed in news of facts that happened in recent years, as already mentioned. happened to be related to garbage and technology using a news item about bags biodegradable.
In addition, topics such as coral bleaching, the processes of ecological succession and the agroecology are also on the rise and can be charged in Enem tests.
Biogeochemical cycles
You biogeochemical cycles involve circulation and natural recycling of elements between living beings and the environment.
Among the subject cycles, another name that may appear when approaching this subject, the ones that appear most in tests are the water cycle, O carbon cycle, the oxygen cycle and the nitrogen cycle.
