Answer:

<u>Food chain as given below</u>

Explanation:

  • A consumer is a living creature in the food chain that eats other consumers and maintains a balance in the food web. Primary producers are all green plants that prepare their food by their ability to utilize the sun's energy and convert that available raw energy into starch in their body by the process of photosynthesis.  
  • These Autotrophs take up the organic matter through their roots in the form xylem and phylum and giving oxygen in the air. They form the base of the food chain on which are dependent Herbivorous like sheep, goat, cow, etc.  
  • The secondary consumers are called the Carnivorous, like the lion, tiger, etc that feed on the bodies of herbivorous. Above this level is that of Omnivorous i.e both plant and animal eaters like the crow, man, and cat.
  • As stated by the law of thermodynamics energy can neither be destroyed nor created but transforms itself. The flow of energy at each trophic level gets successively transferred to the next trophic level from primary to secondary tertiary and so on.
  • Likewise, toxin concentration in trophic levels increased each level upwards and leads to biomagnification that is harmful to the entire food chain.

Humans as species are capable of radically altering the Earth's ecosystem. One goal of the environmental movement is to maintain
dybincka [34]

Answer:

Sustainability, stewardship and sound science.

Explanation:

Sustainability, stewardship and sound science helps in maintain a long-term relationship with the natural world.

Through contributing to air pollution, the release of harmful substances into the air, human activities affect the environment. Such contaminants can have significant impacts on the natural world, resulting in environmental degradation, and issues such as acid rain and harmful ocean algal blooms.

Human should adhere to environmental laws so as to sustain the ecosystem.

describe the factors that control the rate of chemical weathering and those that control the rate of physical weathering
Musya8 [376]
The rate of chemical weathering is controlled by such things as the temperature, the amount of rainfall and the surface area of the minerals which constitute the rocks. Rocks with a finer grain size have more surface area than coarse-grained rocks so are more susceptible to chemical weathering, like a volcanic rock compared to a granite, say. With higher temperatures and greater rainfall, chemical reactions in the rocks are facilitated and this is why, for example argillic (clay alteration) alteration is so well developed in the tropics (in El Salvador for example and also why the lateritic soils develop in countries like Indonesia and can contain economic amounts of nickel for exampl) . A factor which controls the rate of physical weathering could be the development of glaciers which transport rocks in their bed, which shapes these boulders and also scores the rocky surfaces these scrape over as the glacier moves. Alternate freezing and thawing in the spring time in the northern hemisphere can speed up the breakdown of the rock by cracking it or opening up pre-existing joints and faults. 



































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































and also the surface area of the minerals being attacked.

To pay for the compansation, China tried to gather capital by renting ports to the other countries, and allowing the Western powers to took the right of mining as well as building railways in the mainland area. This had caused China to lose even more control of its own land.

Therefore the answer is C.lost even more control of its own affairs to Western imperial powers.
