•Get 1 piece of length wise paper and answer the following
questions.
•General Direction: Write your complete name, grade, and
section. Always read the following questions carefully.
Misspelled words, erasures, and alterations are
automatically considered wrong. Always use CAPITAL
LETTERS.

2. MODEFIED TRUE OR FALSE
WRITE TRUE IF THE STATEMENT IS CORRECT, IF THE
STATEMENT IS FALSE WRITE THE CORRECT ANSWER.
1.The ecosystem, defined as the section of the Earth capable
of supporting life, is actually made up of numerous
overlapping and interconnected ecosystems.  
2.A biosphere is a community of microorganisms, plants, and
animals that interact with one another and with
physical/abiotic environmental elements.

3. 3.The biogeochemical cycle is the process by which certain
compounds change form as they pass through both the
abiotic and biotic components of the environment.
4.A food web is an interconnected food chain in which one
organism eats more than one type of another organism and
may also be devoured by distinct groups
5.The creation of ice crystals/clouds in the atmosphere is
known as condensation.
6. Carnivores are animals that eat plants.

4. 7. Water evaporation through plant stomata is known as
absorption.
8. Autotrophs produce food by using energy from inorganic
substances.

9. Herbivores are creatures that eat other animals.
10. Omnivores are individuals that consume both plants and
animals.
11. Germs are microorganisms such as bacteria and fungi.

5. 12. The feeding relationship between and among living
organisms such that one group becomes the food source for
another is referred to as the food chain.
13. Evaporation converts solar-heated liquid surface water into
gas, which eventually escapes into the atmosphere.
14. Producers are also known as autotrophs because they can
create their own food with the help of external energy sources.
15. Percolation is the melting of ice crystals into liquids in the
form of rain that falls on the hydrosphere or lithosphere.

6. TEST II IDENTIFICATION
16. The division of the nucleus.
17. Division is only observed in plants and animals and results in
the formation of specialized cells known as gametes or sex cells.
18. An anabolic process that turns solar radiation energy into the
usable chemical form glucose, sometimes known as food.
19. For plants and plant-like organisms, karyokinesis occurs
when structures called vesicles grow within the cell's central
region and extend to the cell's opposite ends.

7. 20. A metabolic process that converts glucose into ATP, an
organic substance that the body can use for energy.
 
21. Birth, growth and development, and reproduction are all
physical and metabolic activities.
22. Are deemed primitive since they lack a nucleus and
membrane-bound organelles.
23. Karyokinesis occurs in animal and animal-like organisms
when cytoplasmic division occurs through constrictions that
originate at opposite regions of the central part of the cell.

8. 24. They have a "true nucleus" and additional membrane-bound
organelles that allow for function compartmentalization.
25. The fundamental structural and functional unit of all living
creatures.
26. A freshly created cell expands in size and volume by
absorbing water and dissolved inorganic molecules, synthesizes
genetic material, and produces structures and/or organelles.
27. The stage of cell division in which a single eukaryotic cell's
cytoplasm divides into two daughter cells.

9. 28. The time of reproduction is led by two main processes.
29. Duplicates the parent cell's chromosomal number, causing
the duplicates to be separated from each other by cytokinesis.
30. An energy-rich chemical that the cell uses to power its
anabolic processes.
