Which organism do you think is most likely to be preserved?
Hard parts like bones and teeth are more likely to be preserved. Rapid burial is important in the fossilization process because: It protect a dead organism from physical and biological destruction.
What kind of animals are most likely to be preserved?
Animals with hard parts are more likely to be preserved than animals that have soft bodies. Aquatic animals are more likely to be preserved than terrestrial animals because water ecosystems have greater preservation potential.
What determines about how long ago a fossil organism lived?
determines about how long ago a fossil organism lived. This gives the fossil an approximate age in years. Absolute dating is often based on the amount of carbon-14 or other radioactive element that remains in a fossil.
What are two biotic factors that affect an organism after death?
The three biotic factors that can affect an organism after death are scavengers, predators, and decomposers that can breakdown and destroy the organism.
What are the three biotic living factors in an ecosystem?
Biotic factors are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
What biotic and abiotic factors can break down organisms before they become buried?
Rapid burial protects an organism from biotic factors such as scavengers and decomposers, and from abiotic factors such as sun and wind, allowing the fossilization process to begin. 4. Describe two ways an organism can become a fossil without being buried in sediment. Organisms can be preserved in tar, amber or ice.
How can biotic factors affect an ecosystem?
Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.
What are the 4 biotic factors in an ecosystem?
Biotic and abiotic factors Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
What are biotic factors that affect humans?
How they affect an individual organism depends on what type of organism it is. The other organisms (biotic factors) can include predators, parasites, prey, symbionts, or competitors.
Is human abiotic or biotic?
Humans, like other animals, also require certain abiotic factors to survive and live comfortably. For starters, we need oxygen to breathe—respiration powers our cells.
