After a volcanic eruption, lava flows on the surface of the Earth. After the lava has time to cool, scientists notice that plants are starting to grow on the lava surface. What kind of ecological process could you infer is happening and why?
The correct answer is ecological succession.
For the growth and development of an ecosystem, the phenomenon of ecological succession plays an essential role. A slow procedure by which the ecosystems modify and develop with time is termed as the ecological succession. There are prime two kinds of succession, that is, primary succession and secondary succession.
The phenomenon of ecological succession helps in the colonization of the novel areas, and in the recolonization of the destructed ecosystems, this helps the species to get amend with the modifications taking place in the surroundings and helps them to thrive. The given case is an illustration of ecological succession as the flowing of lava creates barren land, which further helps in the establishment of the pioneer plants. These pioneer species of plants helps in the development of a new ecosystem.
The difference between the cellular make-up of a living organism and an aluminum can is the _____. ability to use energy ability to move bonding structure sensitivity
Answer: The answer would be ability to use energy.
One of the main differences between living and non-living organisms is that the living organisms are able to use energy to maintain homeostasis.
The non-living things such as aluminium can not utilize energy for itself.
However, a living cell uses energy for all its vital functions such as digestion, respiration, et cetera.
ability to use energy
The cellular composition between a living organism and an aluminum can is very different. For starters, only living things have cells, as this is the basic structure of living things. In addition, the cells of living things produce and use energy so that the metabolic processes that allow life to continue happen. For this reason, we can say that the difference between the cellular composition of a living organism and an aluminum can is the ability to use energy.
Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept. Match each characteristic with the species concept(s) to which it applies. Species: 1. biological 2. morphological 3. phylogenetic 4. morphological and phylogenetic 5. biological, morphological and phylogenetic Characteristics: 1) accommodates asexual reproduction 2) not applicable for extinct species 3) relies on similarities of structures 4) used by scientists in classification 5) species acceptance criteria can be subjective 6) based on evolutionary history
Biological species concept defines species as individual in a population that can interbreed and produce viable offsprings. Therefore Biological species concept is not applicable for extinct species
Morphological means in relation to structure therefore, this concept relies on similarity of structure to classify species.
Phylogenetic refers to members having the same ancestor. It classifies species according to common ancestry. Hence it will be based on evolutionary history.
Morphological and phylogenetic- Will accommodate asexual reproduction and species acceptance criteria can be subjective.
Biological, morphological and phylogenetic-Together they are used by scientists in classification
In the context of biological species, it does not support asexual reproduction and is not for extinct species. Morphological species, rely on structure similarities, are used for classification, and have subjective species acceptance. Phylogenetic species are based on evolutionary history, supports asexual reproduction, and has subjective species acceptance criteria.
The three significant concepts of species include the Biological species concept, Phylogenetic species concept, and Morphological species concept.
1) Biological species - This concept does not accommodate asexual reproduction (2) and is not applicable to extinct species (2).
2) Morphological species (or morphospecies) - This concept relies on similarities of structures (3), is used by scientists in classification (4) and the species acceptance criteria can be subjective (5).
3) Phylogenetic species - This concept is based on evolutionary history (6), can accommodate asexual reproduction (1) and the species acceptance criteria can be subjective (5).
The morphological and phylogenetic concepts are used by scientists in classification (4) and their species acceptance criteria can be subjective (5).
All three concepts - biological, morphological, and phylogenetic - are all considered in the broader understanding and definition of species.
