How do predators select their prey?
Most predators choose prey based on the size of the prey, the needs of the predator (how many mouths there are to feed, how long it's been since the predator(s) ate, etc), how strong or weak the prey appears to be, and other such factors. Many predators will target the young and weak specifically because they require less energy to chase, catch and kill.
What does an energy pyramid show us about energy in a food chain?
The difference is that a food chain is one path of energy, and a food web is overlapping food chains. As for an energy pyramid it show that there is less and less food and energy available as you go from the base to the top of the pyramid
What is A and B in appliances?
These are Relative Energy Efficiency (REE) ratings which indicate how much energy they consume to do their jobs as fridges or freezers, washing machines, dryers, etc. relative to other makes and models of the same kind of appliance. An appliance with an REE of A uses less energy than one with a rating of B; an appliance with an REE of B uses less energy than one with a rating of C; an appliance with an REE of C uses less energy than one with a rating of D, etc.
Are there still millers?
Yes, there are still millers today, though the profession has evolved. Modern millers often work in large-scale industrial settings, producing flour and other grain products using advanced technology. While traditional watermills and windmills are less common, small-scale artisanal milling remains popular among some local producers who focus on organic or specialty grains. Overall, the role of millers continues to be important in the food supply chain.
Why is it important to use less electricity?
Because every bit of electrical energy that you use has a price, and it had to be generated by something. If you fail to conserve, you'll be wasting money and resources. Common misconception: People tend to not think about the fact that everything is limited in some way, and harnessable energy on Earth with modern technology is not everlasting, so conserve.
Do predators use more or less energy than producers?
LESS
What ecosystem might have a pyramid of numbers where there are less producers than consumers?
If the producers happen to be large trees, they can be small in number but still have a large biomass, therefore allowing them to support a community of more consumers.
Why is there fewer predators than prey?
because of the passing of energy from one animal to the other. Producers make 1000 energy from the sun. Then as the next animal eats it, like the grasshopper, the grasshopper gets only 100 energy from the plant it ate, and so one. There is less predators because the more the energy lost, the more that the for say, frogs have to eat more grasshoppers to get the same amount of energy that the grasshopper got from the grass. So larger predators have to try hard to eat more, so there is less because not many animals can eat enough of the other animals because of the loss of energy.
Which organisms can offer more energy a producer or a consumer?
Producers, such as plants and algae, convert sunlight into energy through photosynthesis, making them the primary source of energy in ecosystems. They produce more energy than they consume, which is then transferred to consumers (herbivores, carnivores, etc.) that rely on producers for sustenance. While consumers obtain energy from producers, they generally have less available energy due to the inefficiencies in energy transfer between trophic levels. Therefore, producers offer more energy overall compared to consumers.
What trophic level has the greatest amount of energy?
The producers or primary producers (plants, algae) have the greatest amount of energy in an ecosystem. They capture energy from the sun through photosynthesis, making this energy available to other trophic levels.
Why biomass of primary consumers in a food chain is considerably less than the biomass of primary producers?
The biomass of primary consumers is considerably less than that of primary producers due to the inefficiencies in energy transfer between trophic levels. According to the 10% rule of energy transfer, only about 10% of the energy stored in primary producers is converted into biomass by primary consumers, as much energy is lost through metabolic processes, respiration, and heat. Additionally, primary producers, such as plants, capture energy from the sun and convert it into chemical energy through photosynthesis, resulting in a larger overall biomass compared to the energy available for consumers.
Why is agriculture more important than raising livestock for people to produce food energy?
Agriculture is more efficient because in the energy pyramid they're producers while when you raise livestock they get less the energy when they eat producers. Livestock produces less food energy. Agriculture produces more because when you plant you get more of the nutrients to the vegetable or fruit. If livestock they consume the producer and get less of the energy because when the animal loses the energy it goes to the environment as heat and some energy are stored to the previous level
What animal eat cacomistle?
Main Predators Are Bobcats, Ringtails, Raccoons, Cougars, Bears And Coyotes. However, Less Frequent Predators Are American Mink, Black Footed Ferrets, Large Snakes, Large Lizards And Other Animals.
What is the series of steps that show the transfer of energy among living things?
transfer of energy among living organisms is evident in food chain because the producers receive the most energy while the consumers receive less and less energy depends on its position in the food chain.
Why do large animals need to eat more than small animals?
they have less surface area and lose less heat Larger predators have slower metabolism and burn less fat during activity so they need less fuel
Which ecosystem might have a pyramid of numbers where there are less producers than consumers?
In a forest ecosystem, there may be a pyramid of numbers where there are fewer producers, such as large trees, compared to numerous herbivores like insects and small mammals that rely on them for food. In this case, the large biomass of producers supports a greater number of consumers, leading to a situation where the number of individual producers is lower than that of consumers. This inverted pyramid shape can occur in ecosystems where primary producers are large and long-lived, resulting in fewer individuals despite their significant biomass.
There is more what than anything else in an energy pyramid?
There is typically more producers (such as plants) than anything else in an energy pyramid, as they form the base of the food chain and support higher trophic levels. Each subsequent trophic level contains less energy as it is transferred up the pyramid.
