Answer:
Point D
Explanation:
Point D is the point that is most likely to not have any plants growing in it. The reason why this point of the body of water will not have any plants is because of the lack of light. This part of the body of water is dark, with no light penetrating to it. The plants need light to survive, as it is a vital element in the process of photosynthesis. If there isn't any light, the plants can not perform photosynthesis, thus they can not produce their own food, which in turn means that they will not exist in such a place.
Both are a source of energy. So it will be A. Hope this helps!
Sunlight provides energy needed for photosynthesis
Answer:
1. 20 units
2. 4 units
Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.
Sí la neurona se coloca en agua, se hincha. Por cuáles componentes de la membrana celular penetró el agua?. Describe el tipo de transporte.
Al superar estas cantidades se produciría la intoxicación por agua. En este proceso, los riñones se sobrecargan de trabajo y las células se hinchan de forma transitoria. En el cerebro, el hinchamiento provoca una presión contra el cráneo, y por eso una de las primeras señales es el dolor de cabeza.
