Definition of erosion (according to National Geographic): “Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.”
1. Describe the features that water erosion produces in your images (mountains, canyons, deserts, etc?) What do they have in COMMON?
Mountains: Water erosion would create a waterway around the mountains.
Canyons: Water erosion would create more area between the canyons.
Deserts: Water erosion would generally change the desert’s landscape by making the hills more downslope.
What they have in common: They all create changes to the landscape of different areas.
2. You can see water erosion even when you do not see water. How is this possible? Be clear!
This is possible by rain?
- I’m not exactly sure about this question.
Personally I would say it's A (apart from the installation costs which may make it a little expensive) but it does involve certain aspects of D also as wind energy doesn't cause pollution. So either A or D!
Hope I was of help! :)
The correct answer is A. An oak tree
Explanation:
The term "primary producer" is used to describe organisms that can produce their own energy without feeding on others, this includes plants and algae that produce food and energy through photosynthesis using light and other inorganic compounds. Additionally, the primary producers can be identified because in ecosystems they are always on the first level and they are eaten by others.
According to this, the one that is a primary producer is an oak tree because this is a type of plant and therefore can produce its food through photosynthesis different to others that need to feed on other organisms to obtain energy.
