A wide variety of organisms A habitat is a localised environment in which organisms live and which provides all (or almost all) of an organisms needs. Q15. In an ecosystem there is an interaction between what? Plants, animals and their physical environment An ecosystem consists of a community and its environment.

Can you produce a drawing which best represents an atom? Q18. All materials are made up of elements. How many elements are there? Approximation is fine. There are over 100 known elements. Q19. What is formed when atoms of different elements combine? A compound When atoms of different elements combine together they form a compound. For example, two hydrogen atoms combine with one oxygen atom to form the compound water. Q20. How would you best describe the forces which hold atoms together? Bonds hold atoms together. The forces holding together atoms are called bonds. There are different types of bond; there are metallic, ionic and covalent. Q21. How are the atoms in a plastic, such as polythene, arranged? Polythene is a molecule that is a long chain of identical units joined in a line. Q22. Can you give an example of a chemical reaction? Sodium chloride Chlorine is a harmful green gas when it is on it’s on its own and sodium is a highly reactive metal. When they are mixed together they make table salt. Q23. A physical change involves changes in the arrangement and spacing of particles, but no new substance is formed. Can you give an example of a physical change? Water
What are atoms? Well, atoms are the base of any chemical element. Atoms consist of in multiple things, in which these things scientists of the past have discovered, and they are so well known, poems and stories are made about them. In fact, the Periodic Table of Elements is made up of atoms. Atoms are the smallest bit of matter.
When a chemical changes or a chemical reaction occurs there is change in the chemical composition with the substances involved. B) Define energy and discuss energy change. Explain what keeps organisms "alive"
Biotic components of ecosystems include plants, animals, and fungi living in that ecosystem that interact with the environment and other abiotic and biotic components. 8. Create a chart of the major characteristics of and differences between the following terrestrial biomes: Tundra, taiga, grasslands, temperate deciduous forest, desert, monsoon rainforest, tropical rainforest. 9. Create a chart of the major characteristics of and differences between the following aquatic biomes: freshwater ecosystems such as lakes, wetlands, and streams, marine biomes such as estuaries, intertidal zone, neritic zone, open sea zone, and deep sea zone.
Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of
Alongside those animals, plants, fungi, and various microorganisms also tie into the ecosystem. Each one of these living organisms interact and affect one another. each ecosystem has a hierarchy
Within 3 chambers we were able to view the connections between biotic and abiotic factors. Though we cannot see the large scale interactions in the real world, with this experiment we were able to observe the association between the living organisms and nonliving factors. This report shows our discoveries of a simulation where we layout 3 specific ecosystems where we can view the interactions inside and between each of them. In one, the forest biome, it will consist of plants and crickets, another being the first water biome, it will contain the algae eater and a plant, then the final being a stand alone aquatic biome that would allow for unsustained algae growth with a lack of biotic organisms to limit it.
An ecosystem is a combination of living things and also non living things. A biome can be made up of many different biomes like an aquatic biome which can
1. What are the two basic components of any ecosystem? • Abiotic – nonliving environment • Biotic – living components SOURCE: Instructional Material 2. What two physical factors determine the type of biome that is present in an area?
There are three types of chemical bonds: Ionic, Covalent, and Polar covalent. Elements with low electro negativity usually form Ionic bonds, such as salt (NaCl) and usually one element gives up an entire shell to give to the other element. Elements with similar negativity form Covalent
Chemical Bonding S00143856 Emma Butler 22/10/14 Chemical Bonding “We define the chemical bond as an interaction between atoms associated with a collectivization of the valence electronic orbitals” (Bersuker 2010). This meaning that we look at a chemical bond and categorise it according to where the valence electrons are found in the molecules. As the valence electrons determine the chemical properties of the molecule, based on the properties of the molecule we can determine the type of bonding it falls under. The bond is formed by the electrostatic force of attraction between either the electrons or nuclei of the molecules.
Pond Ecosystem Investigation Lab report By: Harshal Buradkar 9 grade Introduction A pond ecosystem consists of abiotic: light intensity of the water, depth of the water, and biotic: fish, plants, bacteria, algae, insects and etc. It also contains water and plants which is the most important part of the pond. Ponds are mostly shallow with the depth of 12-15 feet in which the sun rays can touch the bottom of the pond so that plants can grow.
Introduction The chosen ecosystem is a bush or forest environment with grasses, plants, trees and small mammals and insects. There is little human activity present in this area except for the occasional foot traffic through the area. The abiotic factors of the ecosystem present are soil, sunlight, temperature and a high humidity. The biotic factors of the ecosystem are plants, weed shrubs, insects and small mammals. Materials
When atoms make covalent bonds with one or more other atoms, they create a molecule, e.g. Hydrogen atom have just one electron. They only need one more to complete the first shell so they’ll create single covalent bonds to be stable. H2 can be written as H-H. Another example is H2O: in water molecules, the oxygen shares electrons with H atoms and join together by covalent bonding and be a stable water molecule. There are two kinds of covalent bonding: Simple molecular covalent substances.
Only the substances present in the reactants can end up in the products,
