Explanation:

Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.

As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.

Both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

Habitat may be defined as a type of native environment for which a particular species is best adapted due to natural selection.

Competitive exclusion leads to the elimination of any one species until they do not share different niches.

Therefore, both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

Answer:

A. A resource that is so scarce (in restricted quantity) that it limits the size of a population is called a limiting factor. Any single resource can be a limiting factor to a population size. For example, the amount of water available can affect the number of plants that can grow in an area.

Answer:

Dragonflies are important for our environment.

Explanation:

Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.

Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.

Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

Explanation:

Answer:

Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia,  The temperature is stable year-round, around 27°C (60° Fahrenheit). As you can tell from the name, it rains a lot in these forests. Most tropical forests receive at least 200 cm (80 inches) of rain in a year. Tropical forests generally have a rainy and dry season. Temperate forests occur in the next latitude ring, in North America, northeastern Asia, and Europe, temperature ranges from -30 to 30°C (-22 to 86 F) and the forests receive 75-150 cm (30-60 in) of precipitation per year,

Explanation:

The similarity between reduced space and a lack of food is the option "C" they can both cause animals to move to a new environment.

Prompt population growth continues to be a significant underlying force of environmental degradation and a hazard to the sustainable use of natural resources.

It diminishes the quality and quantity of natural resources through overexploitation, intensive farming and land fragmentation.

Thus, option "C" is correct.

Answer:

this bacteria has a rod shaped form

Answer:

rod-shaped

Explanation:

Bacteria in the genus Thiobacilli are classified within the order Pseudomonadales. They are small, rod-shaped cells (0.5 by 1–3.0 µm) which may be motile or nonmotile. Motility is due to a single polar flagellum. Bergey's Manual (1957) lists nine species, most of which are aerobic.

Answer:

How does a change in food resources model the type of beaks in birds?

Explanation:

We know that phenotype results from the interaction of the genotype and the environment. Any change in the environment produces a change in the phenotype of the animals. By performing this experiment, we probably want to know the influence of the environment on animals. In this particular example, we change a source of food by removing fruit (which would be acting as the independent variable of the experiment) and evaluate its effects on the birds´ beak (the dependent variable). Which of the three different beaks increases their frequencies by removing the fruit, and which one decreases its frequency.

So here, the absence of fruit is acting as a selective ecological pressure on birds. It is modeling birds´ beaks and adapting animals to feed on some other resource.

Answer:

the answer to this is True

Answer:Each and every one of us have several roles. Organisms in a community play other roles too. An organism's role within an ecosystem depends on how it earn its nutrients. Organisms collect their nutrients in very different actions, so they have different roles in an ecosystem.

Explanation:  

The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.

For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.

Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

The producer, the algae, is found at the base of the pyramid, and the black fly larva (an herbivore) is found above it. On the third trophic level, there are carnivores such as the trout, and the kingfisher is on the fourth level.

The ecological pyramid is divided into several types, including the pyramid of numbers, the pyramid of energy, and the pyramid of biomass, and the characteristics of the pyramid vary by ecosystem. The pyramid consists of producers at the basal level, which is the algae, and they produce most of the energy in the ecosystem.

The energy and food are then transferred to the second trophic level, the herbivore level of black fly larvae. The third level is the carnivore level (primary carnivore), where the trout eats the herbivore (black fly larva), and the fourth level is the kingfisher, where it eats the primary carnivore, which is the trout, and this results in the pyramid starting with a broad base of producers and eventually narrowing towards the apex.

Hence, the pyramid begins with a producer (algea), then the herbivore, then the trout, and finally the kingfisher.
