What else can I help you with?
True or false on average about 50 percent of the energy available within on trophic level is transferred to the next trophic livel?
No. About TEN (10) percent of the energy available within one trophic level is transferred to the next trophic level the rest of it is used to grow and develop, except in plants because plants use 100% or close to 100% of the sun's energy to grow and develop.
In an ecological pyramid the biomass of organisms increases at each successive level true or false?
False. In an ecological pyramid, the biomass typically decreases at each successive trophic level. This is due to the loss of energy at each level, primarily through metabolic processes and heat, which results in less biomass available for organisms at higher trophic levels. Therefore, there is generally a greater biomass of producers at the base compared to consumers at the top.
Heredity is the process by which sex cells from true ore false?
False. Heredity is the process by which traits are passed from parents to offspring through genes in the sex cells (sperm and egg).
Is it true or false that ecological pyramids show the relative amount of energy or matter contained within each trophic level in a give food web?
True. Ecological pyramids illustrate the flow of energy or matter through trophic levels in a food web by arranging organisms based on their position in the food chain. Generally, the lower the trophic level, the greater the amount of energy or biomass that can be supported.
Is the greatest amount of energy is available at the producer level is true or false?
True. The greatest amount of energy is available at the producer level, in organisms such as plants that can convert sunlight into energy through photosynthesis. This energy then flows through the food chain to higher trophic levels, with energy being lost at each transfer.
Is entropy is greater at higher trophic level than a lower level?
Yes, entropy tends to be greater at higher trophic levels due to the inefficiencies in energy transfer between trophic levels. As energy is transferred up the food chain, some energy is lost as heat, resulting in higher entropy. Additionally, higher trophic levels typically require more energy input to sustain, contributing to increased entropy.
Because of the constant loss of energy there can be a maximum of 7 trophic levels in a food chain. TRUE or FALSE?
False. The number of trophic levels in a food chain is influenced by factors such as energy availability, efficiency of energy transfer, and ecosystem stability. While energy loss can limit the number of trophic levels, in some cases, ecosystems can support more than 7 trophic levels.
Most of the time animals feed at one trophic level?
False.
True or false on average about 50 percent of the energy available within on trophic level is transferred to the next trophic livel?
No. About TEN (10) percent of the energy available within one trophic level is transferred to the next trophic level the rest of it is used to grow and develop, except in plants because plants use 100% or close to 100% of the sun's energy to grow and develop.
Protista are ecologically important because they process nitrogen through nitrogen fixation is that true or false?
False. While some Protista may play a role in nitrogen fixation, their ecological importance is primarily related to their role as primary producers in aquatic ecosystems, providing food for higher trophic levels and contributing to the overall ecosystem functioning.
Is true or false that Omnivores occupy the same trophic level as carnivores?
Yes, they both lie in the category of consumer.
Is it true or false the first public education law was passed in Pennsylvania?
its false U-U
Laws cannot be passed to implement government policies.?
false
Is Acquired immunity is passed from the mother to the child after birth?
false
The twenty-second Amendment passed in 1933 replaced Prohibition true or false?
False, it repealed Prohibition in 1951
Congress passed the National Emergencies Act in 1976 to keep the president's power in check true or False?
false
Does energy increases at each trophic level from the bottom toward the top of an ecological pyramid?
No, energy decreases as you move up the trophic levels of an ecological pyramid due to energy loss through metabolic processes like respiration and heat loss. This is known as the 10% rule, where only about 10% of energy is transferred from one trophic level to the next.
