Primary streak is the raised groove formed on the dorsal side of the two-layered embryonic disc.

Primary streak is fashioned on the dorsal facet of embryonic disc around fifteenth day of life and is answerable for the formation of notochord and the 1/3 germ layer namely mesoderm. The notochord is shaped through the addition of cells to its caudal cease because the primitive streak degenerates.

The germ layers expand early in embryonic existence, thru the device of gastrulation. for the duration of gastrulation, a hollow cluster of cells called a blastula reorganizes into number one germ layers: an internal layer, called endoderm, and an outer layer, called ectoderm.

The chorion is a membrane enclosing the chorionic hollow space and paperwork from trophoblast cells and extraembryonic somatic mesoderm. The connecting stalk connects the embryo and yolk sac to the chorion and suspends them inside the chorionic sac.

Theorotically, the energy available to detritivores at a steady state according to the image shown is 11110J.

A heterotrophic creature known as a detritivore gets its sustenance by consuming detritus. Detritus refers to the organic debris including dead plant and animal stuff. Coprophagy is a feeding strategy used by detritivores that involves ingesting feces in order to get food. Detritivores include invertebrate insects such as flies, beetles, butterflies and mites as well as soil-dwelling woodlice, earthworms and millipedes along with mollusks such as snails and slugs.

Although the words "detritivore" and "decomposer" are sometimes used interchangeably, they have different meanings. Detritivores are essentially a subgroup of decomposers. Real decomposers, such as fungi, bacteria, or protists, adopt saprotrophic feeding, in which they receive nutrients by extracellular digestion instead of oral ingestion. This is in contrast to detritivores.

Detritivores and decomposers break down all of the dead and decaying matter in the ecosystem. As a result, they considerably contribute to the cycling of nutrients and are an essential part of the majority of biogeochemical cycles, including the nitrogen, phosphorus and carbon cycles.

Detritivores are present at all trophic levels in an ecosystem because they consume materials produced by primary producers as well as by herbivores and carnivores. Detritivores are an essential part of the ecosystem energy cycle because they typically take energy from secondary consumers in addition to eating energy from other species.

The total net energy generation shown in the figure is 10000 + 1000 + 100 + 10 = 11110J.

Answer: An organism’s niche is determined by its , which is it’s physical environment called Habitat.

Explanation: A niche is a part a species perform in the ecosystem. In other words, a niche is how an organism “makes a living.” A niche will add the organism's capacity in the flow of energy within the ecosystem. This includes how the organism generates its energy.

The habitat is the natural area where a species lives. Many circumstances are used to represent a habitat. The common amount of sunlight collected each day, the range of annual warmth, and average yearly rainfall can all represent a habitat.

An organism’s niche is determined by its. Which is its physical environment by its habitat.

The living area of an organism with easy access to food, water, and shelter is known as the habitat of the organism. Here all the suitable abiotic and biotic conditions meet the requirements of the organism. The animal reproduces only in there natural habitat as it gets suitable mates in the area.

There are four types of habitats freshwater, marine, and coastal habitat. Rivers, lakes, streams, and ponds are a few examples of freshwater habitats. Seas and oceans are the largest marine habitats whereas the area where the coastal line meets the land is the coastal habitat.

In terms of their place in the food chain, fungi and mammals are most similar. Animals and fungi do not generate food like plants do. Therefore, outside food sources provide a source of energy for both mammals and fungus.

In addition, research published in 1998 by experts suggests that fungus descended from mammals 9 million years after plants. This implies a closer relationship between fungi and plants.

The statement indicating that 'environmental changes may likely cause different genetic mutations' is likely true about environmental changes (Option 3 is correct).

The association between environmental changes and genetic mutations is due that environmental factors such as excessive temperature or light conditions, for example, may cause stress on the organism, and therefore they are triggers of genetic mutations.

Mutations are the consequence of the alteration in the genetic material that forms the genome of the cells (either gametic germinal cells or somatic cells) of an organism and these changes depend on the homeostatic control (state of internal equilibrium) in which the organism lives.

The correct answer is The two hormones have opposing actions on various target tissues. Epinephrine increases blood flow to skeletal muscles and decreases blood flow to smooth muscles in the digestive system during the flight or flight reaction. Auxin encourages the growth of apical buds while inhibiting the growth of lateral buds in order to achieve apical dominance.

The adrenal glands and adrenergic neurons produce epinephrine, a hormone and neurotransmitter that is generally referred to as adrenaline. Two hormones generated by the adrenal medulla—epinephrine (adrenaline) and norepinephrine—start the body's fight-or-flight response (norepinephrine).

The airways open up as a result of the adrenaline reaction, giving the muscles the oxygen they require to fight or flee danger. Auxin, on the other hand, induces apical dominance, which is when a shoot's suppresses the growth of lateral buds to enable vertical growth.
