Ecosystem Quizzes Online & Trivia

The answer to this question is 4. The level of this food pyramid that represents the largest amount of organisms would have to be the producers. Although this question may have tricked you, it is the producers who always have the highest number of organisms in the food pyramid. In order for consumers to be consumers, they must have producers who product things for them to consume. Consumers can not thrive or even exist without the producers. So the tertiary consumers and the secondary consumers would not be there if there was no food to eat. The tertiary consumers are the ones that make sure that there is enough food for the other consumers.

There are 8 ecosystems in that web some can eat each other and some can not

The correct answer to this question is C. Out of all of the answers given, "Community" fits the definition best and is most similar to the definition of a population. A biome is a naturally occuring community of flora and fauna in a habitat, such as a forest or jungle. An ecoprovince includes an area of a one climate, such as a mountain range or plateau. A specifics is a group of living organisms that can breed with each other and exchange genes. An ecotone is the boundary between two distinct biomes, such as the line between a flat meadow and a tree-filled forest.

The answer to this is letter D. Niche refers to the type of roles that the various organisms play in order to keep the ecosystem in good, working order. If in case you do not understand this well yet, think about what you do in school. Do you play in a school band? Are you a singer? Your role in school is your niche. This is the same with the organisms that can be found in the ecosystem. They have their own niches too. For example, is a certain organism a decomposer? Is it an organism that produces the food that consumers need? These are roles that organisms will continue playing as long as the ecosystem is working well.

The above mentioned means Abiotic meaning the non-living part of the environment

1. Sea urchin use much of their energy for life processes

Birds might compete with Hawks for space, squirrels for energy

Rabbits because its on the lawn and rabbits eat grass

70 and 7 kcal of energy will be available for the Sheephead and fish.

This graph shows that paramecium B is the predator, and paramecium A is the prey. So, to figure this out, you have to look at two things: the populations, and when each paramecium was introduced to the beaker. Paramecium A is introduced at day 0. There’s a huge peak in the population of this paramecium over the next two days. Paramecium B is added on day 2. Paramecium A’s population plummets over the next three days as paramecium B’s population slowly grows. By day 5, there’s no paramecium A left. Paramecium B survives for another day and a half before dying off. The only way this kind of graph could come around would be if paramecium B is eating paramecium A.

The answer is CC. The amount of energy at each trophic level

It is more realistic to consider food webs, a more complex representation than a food chain. the chain does not take acocunt of all contributors. the producer will consume several foodstuffs, the species to be eaten will be consumed by more than one other species. The web takes into account contributors that are part involved in one chain, and part involved in another. the ecosystem is always more complex than a simple linear construction can convey. So although option 2 is correct, option 4 gives more useful information about the ecosystem.
