Ecosystems

(any period)

Electrons are added to the same shell, therefore the nuclear charge is greater. Electrons are closer to the nucleus so have a greater attraction to the neucleus as you go across a period.

(enough to get you 3 marks, use this always for this type of question).

glass is nonliving. The non-living factors that are part of the ocean ecosystem include water, the substrate (rock or sand), and the minerals and gases dissolved in the water.

Keystone species play a crucial role in maintaining the structure and function of an ecosystem. They have a disproportionate impact on the community relative to their abundance, often influencing species diversity and ecosystem stability. Their presence can regulate population sizes, enhance biodiversity, and promote overall ecosystem health.

Appearance is not an accurate indication of potability [ drinkability -- fit for human consumption ].

For example, a powerful poison can be a clear, transparent and sparkling liquid in a glass, looking exactly like a glass of refreshing water. But what a difference healthwise !!!

The above answer does not tell much about the health of an ecosystem, although it is important to remember when looking for a source of drinkable water. A healthy freshwater ecosystem will have little pollution, few invasive species, and an abundance of both plant and animal species. The presence of leeches usually indicates good quality water.

Habitat

People can help the ecosystem by reducing waste, conserving water and energy, planting trees, reducing the use of harmful chemicals, and supporting conservation efforts. Additionally, practicing sustainable agriculture, reducing plastic use, and supporting policies that protect natural habitats are also important ways to help the ecosystem.

Detritus feeders play a crucial role in breaking down dead organic matter, such as fallen leaves and dead animals, into smaller particles. By doing so, they help to recycle nutrients back into the ecosystem, making them available for plant growth and sustaining the food web. They also contribute to the decomposition process, which helps to maintain ecosystem health.

It is important that the population size of animals and plants to remain stable so the food chain runs fluidly. If you had a major increase or decrease of a species then that would cause drastic change to the environment. For example: given the food chain of grass, a grasshopper, a frog, a snake and a hawk if the grass population went under then the grasshopper, frog, snake and hawks population would drop because the grasshopper would eat the grass and without grass than the population would decrease along with the other. But if the frog population decreased then the grasshopper population would increase from the lack of frogs but the grass would decrease from the overpopulating grasshoppers while the snakes would decrease with the hawks. After a while though, despite the drastic over- or underpopulation, the environment would find a way to get itself stable once more.

1. Rocks and minerals in the soil.
2. Water bodies such as lakes, rivers, and oceans.
3. Air that contains gases like oxygen and carbon dioxide.
4. Sunlight, which provides energy for photosynthesis.
5. Artificial structures like buildings or roads.

It's a biotic factor because it's a living factor in an ecosystem, which would be a desert.

Biotic Factor-living factors

Abiotic Factirs-non-living factors

Organisms with close biochemical similarities likely share a more recent common ancestor, leading to a stronger evolutionary relationship based on a more recent divergence from a common gene pool. This shared genetic heritage results in similar biochemical pathways and molecular mechanisms, reinforcing the evolutionary relationship between closely related organisms. In contrast, organisms with greater biochemical differences likely diverged from a common ancestor further back in evolutionary history, leading to a weaker relationship due to more distinct genetic and biochemical characteristics.

Plants are the organisms that produce their own food through photosynthesis and supply other organisms in the ecosystem with energy and nutrients. They are the primary producers in most ecosystems.

Some organisms have no bones to leave behind. Even so, the conditions have to be perfect for a fossil to be formed: they have to die in a riverbed; no other animals can damage the bones; sedimants have to slowly build up without the bones being moved ; and finally they have to be discovered by a person.

The maximum number of individuals a species can support in a given area is known as its carrying capacity. This limit is determined by factors such as available resources (food, water, shelter), competition with other species, and environmental conditions. As the population approaches its carrying capacity, individuals may experience increased competition and resource scarcity, which can lead to a decrease in population growth or even a decline in numbers.

False. A habitat is the physical environment where a species lives, while the role a species plays in a community is known as its ecological niche.

In an ecosystem, the seven non-living things include sunlight, air, water, soil, temperature, rocks, and minerals. These abiotic factors are essential for supporting life within the ecosystem but do not possess characteristics of living organisms.

A productive day is one in which you accomplish tasks and make progress towards your goals. It involves focusing on important activities, managing your time effectively, and staying motivated to complete your responsibilities. Ultimately, a productive day leaves you feeling satisfied and accomplished.

They provide materials organisms need to build their bodies.

No, energy decreases as you move up the trophic levels of an ecological pyramid due to energy loss through metabolic processes like respiration and heat loss. This is known as the 10% rule, where only about 10% of energy is transferred from one trophic level to the next.

crops that grow more reliably (apex)

1. Deforestation: People cutting down trees for agriculture or urban development disrupts habitats for many species and reduces biodiversity.
2. Pollution: Dumping waste materials into rivers, oceans, and soil can harm organisms and disrupt the balance of ecosystems.

it is not a stable ecosystem

Fundamental niche is the natural habitat of a species, where it can easily get food for its energy requirements, and can mate and reproduce without the fear of predators

Realized niche is the environment that a species finally gets because of many limiting factors
