Plants like the stinging nettle seen here have sharp, needle-like hairs that inject a burning chemical into animals that touch the stems or leaves. These hairs are used for A) protection. B) reproduction. C) photosynthesis. D) attracting insects.

Answers

Answer 1

Answer:

A. Protection

Explanation:

These plants have this external protection system to protect them against being eaten by these animals.

In cases where these plants are approached to be eaten by these animals, these systems which in this case are these hairs tend to make an effort by discomforting the approaching animals.

The animals upon sensing this discomfort retreat from feasting on these plants which thus prolongs their lives and prevent them from being eaten by these animals

Select an ecosystem that is familiar to you and describe the biotic and abiotic factors that exist there?

Answers

Answer:

Forest Ecosystem

An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.

Biotic Factors by Type

The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:

shrubs , flowering plants , ferns , mosses , lichens , fungi , mammals , birds , reptiles , insects , worms , microbes

Abiotic Factors by Type

The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.

Biotic Factors by Function

Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.

These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.

These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.

Abiotic Factors by Function

The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).

Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.

An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.

What is a Grassland Ecosystem?

A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.

The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.

Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.

D. True to all elements, they have the properties after they are combined.​

The correct option is D.

According to natural selection theory, Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes Adaptations beneficial at one time should generally be beneficial during all other times Well-adapted individuals have more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals. Adaptations beneficial in one habitat should generally be beneficial in all other habitats

Answers

Answer:

The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.

Explanation:

Adaption in natural selection is a species, time-specific, and habitat-specific process. So, it means if a species is adapted to genetic changes in a particular habitat, it is not necessary that all other species also adapt to similar genetic changes.

Similarly, if a species has beneficial adaption for a particular habitat, it is not necessary it will be beneficial for the other habitat as well.

Thus, natural selection leads to the well-adapted individual that leave more offspring and contribute more to the gene pool.

He knows he could last without food up to a month, but if he didnt have water to drink he would be dead within a week.

Why do you think drinking seawater killed the sailor faster than not drinking any water at all?

Answers
