Scientists use fossils to learn about organisms' lives and evolutionary relationships, to understand geological change, and even to locate fossil fuel reserves.
A nucleus cytoplasm that’s the answer
Answer:
any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the 81 stable elements, in addition to over 800 radioactive isotopes, and every element has known isotopic forms. Isotopes of a single element possess almost identical properties.
Explanation:
The ability to blend into the surrounding environment can come in handy when trying to avoid a predator, especially for those animals with little else in their defense arsenal.
Walleye like to eat minnows. In turn, the minnows feed on scuds (zooplankton) which eat algae (phytoplankton). In this system, the zooplankton are the primary consumer.
Zooplankton is animal plankton that is bigger in size than phytoplankton. The zooplankton is made out of both primary consumers which eat free-drifting algae, and secondary consumers, which feed on other zooplankton. These creatures are consumers since they should eat preformed organic compounds to endure in the ecosystem. Thusly, zooplankton then becomes nourishment for a bigger, secondary consumer like fish. Zooplankton incorporates microscopic and macroscopic life organisms and is of various kinds, and their food sources are vary extensively.
