1- Animals survive when they compete. In limited resources, animals either compete, kill or co-operat. There are 3 ways animals complete with each other to get access o limited resources. These ways are:
- Parasitism – In this relationship, one animal gets benefit and the other gets hurt.
- Mutualism – in this interaction, both organisms benefits each other and survives.
- Commensalism- In this interaction, one organism gets benefit whereas the other gets nothing in return.
2- Living organisms are classified as:
- Producers
- Consumers
- Decomposers
Producers are the energy generators. They are the biggest source of energy for other levels. Consumers feed on producers and other animals. And the end, when consumers die, decomposers feed on them, break down their bodies and mix it with soil increase its fertility and the cycle of energy flow goes on.
Answer:
D. Dehydration synthesis
Explanation:
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds between monosaccharides. A dehydration synthesis reaction forms a bond between carbon atoms in two monosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
Explanation:
Winds are caused by low and high pressure zones, mainly due to temperature differences of atmospheric air in different regions. Air moves from high to low-pressure zones causing winds.
Local winds, as the name suggests, are winds due to regional temperature differences. An example is sea breeze caused by temperature differences over land and sea in the region.
Global winds, on the other hand, are caused by large pressure systems across the planet. These are mainly caused by differences in how the sunlight ‘hits’ the planet at different latitudes – due to earth’s spherical nature- causing differential heating of the earth. These winds travel great distances causing trade winds.
