Are dead things abiotic or biotic?

Are dead things abiotic or biotic?

Dead organisms are not abiotic. Some people think that if an organism is no longer alive, it cannot be considered biotic. However, if something used to be alive, or was part of a living organism (such as a bone, or hair), it is still considered biotic.

Why is a shell considered to be biotic?

In biology, a shell is defined as a protective structure of mollusks and crustaceans. A shell is considered to be biotic because it came from something living. Shells are not in fact alive as they are made of calcium carbonate and in some cases α-chitin, two non living materials.

The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc…

What can cause an ecosystem to become unhealthy?

Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3).

What will happen if there is an imbalance in the food chain?

When one of the links (species) in a food chain is no longer present (for example a species goes extinct or a feral animal takes over), the food chain breaks. Sometimes, this can cause other animals in the food chain to disappear as well and the whole ecosystem can become imbalanced or even collapse.

Does every food chain depend entirely on a single species?

every food chain depends entirely on a single species.
