They are changed because of the environments changing
Answer:
Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.
If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.
A combination of two or more metals is called and Alloy.
Answer:
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Explanation:
- Fossil fuels such as coal, petroleum and natural gas are produced and stored in the geosphere. i.e. the part of the Earth that includes the Earth's interior, landforms, rocks and minerals.
- Fossil fuels, extracted from the geosphere are burned to generate energy.
- Combustion of fossil fuels releases the stored carbon into the atmosphere in the form of carbon dioxide.
