1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.
2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).
3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.
The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.
4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).
5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.
6. Trophic level is the position of an organism in the food chain.
Science has shown that smoking causes cancer. which is an example of how society responded to this information
Answer:
The most appropriate answer would be B. Have factories recycle water.
Recycling of water refers to the process which processed the waste water and convert it to reusable form.
It can be reused for various purposes:
- Agriculture: irrigating different types of crops, aquaculture etc
- Urban uses such as irrigating golf courses, public parks, private gardens, roadsides, cleaning of roads, systems involved in fire protection, washing of vehicles, toilet flushing, snow-making etc.
- Industrial uses: processes that involve water like cooling towers, washing, dust control etc.
- Environmental uses: It also helps in recharging the surface and ground water, marshes, wetlands, silviculture, wildlife habitat etc.
- Potable: Recharge aquifers ultimately leads to increase in quantity of drinking water.
Hence, having factories which recycle water helps in keeping the freshwater resources renewable.
Potential energy=PE
PE=mgh
m=mass in kilograms.
g=9.8 m/s
h=height in meters
Data:
mass=500 Kg
h=110 m
PE=(500 Kg)(9.8 m/s²)(110 m)=539000 joules
No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP<span>). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called </span>aerobic respiration<span> and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
