A food chain is a simplified way to show the relationship of organisms that feed on each other. It’s helpful to classify animals in a simple food chain by what they eat, or where they get their energy.

Green plants, called producers, form the basis of the aquatic food chain. They get their energy from the sun and make their own food through photosynthesis. In the Great Lakes, producers can be microscopic phytoplankton (plant plankton), algae, aquatic plants like Elodea, or plants like cattails that emerge from the water’s surface.

Herbivores, such as ducks, small fish and many species of zooplankton (animal plankton) eat plants. Carnivores (meat eaters) eat other animals and can be small (e.g., frog) or large (e.g., lake trout). Omnivores are animals (including humans) that eat both plants and animals. Each is an important part of the food chain.

In reality, food chains overlap at many points — because animals often feed on multiple species — forming complex food webs. Food web diagrams depict all feeding interactions among species in real communities. These complex diagrams often appear as intricate spider webs connecting the species.

This lesson demonstrates that changes in one part of a food chain or web may affect other parts, resulting in impacts on carnivores, herbivores, and eventually on producers. An example of this might be the harmful effects of pollution. The point that should be made is that when something disrupts a food web, humans should try to understand and minimize the disturbance. Students should also come to recognize that humans, too, are part of this complex web of life.

Explain, in detail, the difference between a population and a community

Answers

Ecology is a branch of Biology that studies the interrelationships between organisms (plants, animals) and their environment.

The word comes from the Greek word oikos which means "house."

A Population is group of organisms of the SAME species living in the same area at the same time and sharing a common gene pool. This group is potentially able to interbreed with one another.

In ecology, the term Community refers to the populations of animals and plants that live within a specific region under similar environmental conditions. These populations of plants and animals live and interact with one another and their environment. Between Humans, the term Community generally refers to a group of people living in the same locality or sharing some common characteristics (i.e. ethnic, cultural or religious).

What is ABO blood grouping ?

The blood grouping can be defined by the presence of surface antigens in the red blood cell which are  A and B. The gene present on the parent chromosome can determine the blood group.

Blood type A represents to the presence of gene A, and its genotypic expression can be A/A or A/O.

Type B blood group where genotype is represented as B/B or B/O, is due to the presence of a gene containing the B antigen.

AB blood group which is codominant- has one gene for A and another for B, with genotype A/B.

Blood type O is mainly characterized by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

The way it gets food is a biological aspect of an organism's niche.

What is Biological niche?

The term "niche" in ecology refers to the function an organism performs within a community.

The physical and environmental requirements (such as temperature or topography) and interactions with other species that a species must tolerate make up its niche (like predation or competition).

For instance, the tiny songbird from North America known as the Kirtland's warbler which is scarce, has an extremely constrained niche. It exclusively builds its nest amid young jack pine trees (Pinus banksiana), whose seeds need regular wildfires to germinate.

Therefore, The way it gets food is a biological aspect of an organism's niche.

D - temperature

Answers

Answer:

option C. all of these.

Explanation:

The main sequence period is when a star will experience the majority of its life. Helium is currently being created via nuclear fusion from hydrogen. Thus, option C is correct.

What is a complete cycle of a particular star?

The main sequence phase, which our Sun is in, will be entered by the star if it is large enough to fuse hydrogen atoms into helium.

The mass of a star determines its life span. The life cycle of an object decreases with increasing mass.

The amount of substance present in a star's nebula, the enormous cloud of gas and dust from which it emerged, determines the star's mass.

The temperature and pressure rise when the material compresses, just as they do during formation. The freshly created heat briefly overcomes the effect of gravity, pushing the star's outer layers outward.

Therefore, As a star goes through this cycle their luminosity, brightness, temperature changes.
