Because you know someone might be in danger. Guide dogs are really important for their owners, its a job. They're not just pets for them but also someone they depend on and someone they trust.
Hello,
1 This suggests that the problems in Johannesburg are not local and specific only to this large urban area, but exist elsewhere. More importantly, Paton suggests that these problems will continue to increase as urbanization continues in South Africa unless the changes he suggests are implemented.
2 The miners are unsatisfied with the working conditions, including the separation from their families and the unfair distribution of wealth from the mines. After the narrative voice says that all is quiet another voice retorts that only fools are quiet. This makes an interesting contrast with John Kumalo with his powerful voice, but lack of action and Arthur Jarvis and his eloquent letters. Both of these men use words but do not follow the words with action. Kumalo out of fear and Jarvis due to his untimely death. Paton could be making the point that words, regardless of how eloquently spoken or written, may begin change, but only action will ultimately bring about that change.
3 Jarvis provides milk to the children of the village. Jarvis begins to realize the predicament of the natives and how that predicament really involves all of South Africa, white and black. He realizes,like his son, that everyone must work together and that the native population must be educated, one of his son's goals.
4 <span>The novel thus ends on a note of hope: Kumalo awakes from a both a literal and a metaphorical darkness into dawn. Therefore, while Paton ends the novel with the question of when Africa itself will emerge from its metaphorical darkness, there is nevertheless the assumption that the emergence into a dawn is inevitable. The question of when this emergence from darkness will occur is the only question that Paton can now pose.</span>
Answer:
True.
Explanation:
Pyramid of energy is also referred to as food pyramid and it's a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
A list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary (top) consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food web. Thus, producers are mainly known as the foundation of a food web (chain) and are at the top.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
