Identify two reasons why insects sometimes must be controlled?
Insects must be controlled because they can over populate. Some can be quite harmful to humans and others are just plain pests.
Where can you get the energy bulb in moo moo generation x?
Where you can get your energy bulb in moo moo generation is level of your opponent and must play it in full house.
How many babies can a lizard have?
most lizards lay around 10- 25 eggs but it depends on the following food source must be high to have more eggs fertile and must be in a secluded spot away from predators
Why must the burrow of the otter be above the level of the water in the rivier?
The burrow of the otter must be above the water level to protect it from flooding and to provide a safe, secure place for raising young. Elevated burrows also offer a refuge from predators and create a dry environment for resting and denning. Additionally, being above the water allows otters to easily access the burrow while maintaining a connection to their aquatic habitat for hunting and foraging.
What do chordates eat?
Chordates have a wide range of feeding habits depending on the specific species. Some chordates, like humans, eat a varied diet of plants and animals. Others, such as fish, may be herbivores, carnivores, or omnivores. Some chordates, like sea squirts, are filter feeders, while others, like hagfish, are scavengers.
In food chain and web what trophic level must you have more of than other?
the primary producer
Why is it that only part of the energy store in one tropics level is passed on to the next level?
Because every organism, upon consuming a resource, must expend some energy in order to digest/process that resource. Thus not all energy is passed from trophic level to trophic level.
Why does the amount of energy decrease as you move up the energy pyramid?
Energy decreases as you move up the energy pyramid due to energy loss at each trophic level through respiration, heat loss, and incomplete digestion. Organisms at higher trophic levels must consume more food to meet their energy needs, resulting in less energy transfer to the next trophic level.
What is needed for an ecosystem to create stability?
An ecosystem needs biodiversity, nutrient cycling, energy flow, and dynamic interactions among its components to create stability. These elements help maintain resilience in the face of disturbances, such as natural disasters or climate change.
Why do different tropic levels have different amounts of energy?
Different trophic levels have different amounts of energy because energy is lost as it moves up the food chain. Organisms at higher trophic levels must consume a larger amount of lower trophic level organisms to obtain enough energy to sustain themselves. This inefficiency in energy transfer limits the amount of energy available at each trophic level.
What trophic level represents the largest biomassin this ecosystem?
The producers, which are usually plants, represent the largest biomass in an ecosystem. They convert sunlight into energy through photosynthesis, providing food for consumers at higher trophic levels.
How is the energy loss from one trophic level to the next reflected in the pyramid of numbers shown in the transparency?
In a pyramid of numbers, the number of organisms decreases at higher trophic levels due to the energy loss as it moves through the food chain. This is because each trophic level must consume more individuals from the level below to meet its energy needs, resulting in a decrease in the total number of organisms as you move up the pyramid. This reflects the decreasing efficiency of energy transfer from one trophic level to the next.
Why must there be more organisms at the bottom of the pyramid of numbers at the top?
There needs to be more organisms at the bottom of the pyramid of numbers because each trophic level requires energy from the level below it, resulting in a decrease in available energy as you move up the food chain. This means that more organisms are needed at lower levels to support the energy requirements of those at higher levels.
Why is so little of the energy from one trophic level transferred up to the next trophic level?
Energy is lost as heat through respiration, metabolism, and waste production as it moves up the food chain. Each trophic level can only convert about 10% of the energy it receives into biomass that is available to the next trophic level, resulting in an overall inefficiency in energy transfer.
What does auto trophic mean?
auto must be meaning automatic,they can make there own food and trophic must be ecology of or involving the feeding habits or food relationship of different organisms in a food chain. by sharandeep bose
Why must there be more biomass at the lowest trophic level?
Consumers do not use 100% for growth as some of the energy they use is used to maintain body temperature but also to contract muscles. As energy cannot be created or destroyed but only transferred the amount of energy as you go up the chain must decrease, so the primary producer must have the most biomass.
Why are matter and engery transferred through an ecosytem?
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
