What else can I help you with?
Which of the following best explains why the number of organisms at each level decreases while moving up the energy pyramid?
because the larger animals higher up the energy pyramid require more food and energy therefore the population of the species below it can support less of the larger species.
Does size affect metabolism?
Size does effect metabolism rates. The smaller the animal the less energy its metabolism expends. Bigger animals must have a more active metabolism to regulate themselves, and it correlates with expected lifespans.
How are plants similar to animals?
Plants and animals are both living organisms that require energy, nutrients, and water to survive. They both have cells and are capable of reproduction. Additionally, they both respond to external stimuli in order to adapt to their environment.
Why do animals need a continuous supply of oxygen?
Animals need a continuous supply of oxygen because it obtains energy from their food. To acquire such energy from food, cells in animals require a steady supply of ATP in order to function. To produce this ATP, cellular respiration requires oxygen. Without ATP, cells and the organism will die so therefore, animals need a continuous supply of oxygen to survive.
Why are desert animals small?
Desert animals are often small because being small helps them conserve water and energy in the hot and dry desert environment. Smaller animals have a larger surface area relative to their body size, which helps them dissipate heat more efficiently and reduces the amount of water they need to survive. Additionally, smaller animals require less food to sustain themselves, which can be scarce in the desert.
What do animals and plant require in order to grow and survive?
Animals and plants require water and food to grow and survive. This is because they must get their energy by eating food or by making it.
Why do smaller animals have a higher metabolism compared to larger animals?
Smaller animals have a higher metabolism compared to larger animals because they have a higher surface area-to-volume ratio, which means they lose heat more quickly and need to generate more energy to maintain their body temperature.
Why does our energy depend on body mass?
Our energy needs depend on body mass because larger bodies require more energy to sustain basic functions like metabolism and movement. This is because more tissue and cells need to be supported and fueled by energy in larger bodies. Smaller bodies have less mass to maintain and therefore require less energy.
How does animals obtain energy?
Animals obtain energy by what they eat. It is all a big cycle, the sun(main source of energy) gives energy to the grass which gives energy to the cow, though in smaller amounts.
Which of the following best explains why the number of organisms at each level decreases while moving up the energy pyramid?
because the larger animals higher up the energy pyramid require more food and energy therefore the population of the species below it can support less of the larger species.
Why do animals require higher rate of respiration then plants?
Animals require higher rate of respiration as they move from one place to another and therefore they need more energy. There the rate of respiration in animals is than in plants. They require more enrgy.
Why human must eat?
Humans are animals, and all animals require energy to move, and reproduce. They obtain that energy from ingesting food, and digesting it.
Most plants and animals require food and oxygen to live. Plants and animals primarily use the oxygen to convert their food into?
energy
Does anabolism require energy?
Yes, anabolism requires energy because it involves building larger molecules from smaller ones. This process is energy-consuming as it requires input of energy to form new chemical bonds and create complex structures. This energy is typically sourced from ATP or other sources of cellular energy.
Why are there usually few organisms at the energy pyramid?
In a stable ecoystem, there should always be more producers than carnivores. For one, there has to be more energy, because your energy flow has to reach the top of the pyramid through your primary, secondary, etc. consumers. There has to be more at the bottom because the organisms at the upper levels have to have a food source. How would the jungle look if there were 100 tigers and only 1 plant?
Why do animals need food to stay alive?
Animals need food to stay alive because food gives them nutrients and energy. Nutrients and energy are both important because they help the bodies of animals function.
Why doesn't the energy from plants go into the animals that eat it?
because you can't transfer energy
