A

Example of photo- autotrophs(plants) - are organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in callular functions such as biosynthesis and respiration.

Called study Inside body of animals
Physiology

Anatomy
33
Naturally occuring water that is not salty.
Fresh water
34
Are salt water, meaning they have higher concentrations of dissolved salts.
Marine water
35
Is a part of a river that meets the sea. It is water accuring in a natural environment that has more salinity than freshwater, but not as much as seawater.
Brackish water
36
Is a wetland that is dominated by herbaceous plants rather than by woody plants.
Marsh
37
Is a linear network of links in a food web, often starting with an autotroph, also called a producer, and typically ending at an apex predator, detritivore, or decomposer. It is not the same as a food web.
Food chain
38
are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. 
Freshwater ecosystem
39
List of Freshwater in our regions (mindanao)
Ponds and lakes Streams and rivers Wetland
40
List of Freshwater resources
Lake and ponds Rivers and streams Reserviors Wetland Groundwater
41
a large natural or artificial lake used as a source of water supply.
Reserviors
42
- it is they provide the majority of global drinking water resources. - it is povide opportunities. - And means transportations.

Fish Amphibians Aquatic plants Invertebrates(animals without backbone) Lives in?
Organisms that lives in freshwater ecosystems
46
Majors groups of organisms lives/ inhabit freshwater ecosystems
- Vertebrates - Invertebrates - Plants, algae, fungi, and bacteria. - Phytoplankton and zooplankton - Periphyton, macrophytes(aquatic plants), insects, fish - Amphibians
47
Are the bodies of water that fill depressions in the earth surface. May be further describes by their origin and classified by trophic statis according to their characteristics.
Lakes
48
Are lakes, often mam-made, that control water flow for hydroelectric power generation, flood control, and/or municipal water supplies.
Reservoirs
49
are bodies of water (usually fresh water, but occasionally brackish), which can vary in size between 1 square meter and 2 hectares (this is equivalent in size to about 2.5 football pitches), and which holds water for four months of the year or more.
Ponds
50
Differentiate ponds and lake
- difference in size - Lake are natural but ponds are artificial created or man made. - ponds and lakes are different in terms of temperature, because ponds can same temperature from top to bottom whilelakes can have dramatically different temperature from surface to bottom waters.
51
Lakes defination
- Larger - Deeper - May have dramatically different temperatures from the surface to the bottom waters. - Light generally does not reach bottom at deeper points. - It affects local climate if it is large enough.
52
Ponds definations and characteristics?
- Smaller - Swallower - top and bottom waters generally have the same temperature. - light generally will reach the bottom in all areas of the pond. - Ponds are usually man-made, tend to be greatly affected by local climate.
53
Similarities of ponds and lakes
- Ponds and lakes may have limited species diversirty since they are often isolated from one another and from other water sources like rivers and oceans. - Lakes and ponds are divided into three different "zones" which are usually determined by depth and distance from the shoreline.
54
It is exist water or fresh water, that a seasonal and only lasting just a couple of months (such as sessile pools).
Ponds
55
It is existing water or fresh water that may exist for hundreds of years or more
Lakes
56
is typically shallow with a soft and mucky bottom. Rooted plant growth is abundant along the shore and out into the lake, and algal blooms are not unusual. Water clarity is not good and the water often has a tea color. If deep enough to thermally stratify, the bottom waters are devoid of oxygen.
Eutrophic lake
57
are low in nutrients and primary production, rich in oxygen throughout, and have good water clarity.
Oligotrophic lake
58
are low in nutrients and primary production, rich in oxygen throughout, and have good water clarity.
Oligotrophic lake
59
Waters with more nutrients and, therefore, more biological productivity. 
Mesotrophic lake
60
3 types Lake Zonation
1. Littoral 2. Limnetic 3. Profundal
61
It is the lake shoreline where sunlight can reach the bottom.
Littoral
62
It is commonly recognized as the open waters.
Limnetic
63
It is deep water where sunlight does not penetrate.
Profundal
64
What is Epilinion
It is a Surface water.
65
What is hypolimnion
A bottom water.
66
What is metalimnion?
It is transitional area between the bottom and surface water.
67
It is topzone near the shore of a lake or pond. This zone is the warmest since it is swallow and can avsorb more of the sun's heat.
Littoral zone
68
It is near- surface open water surrounded by the littoral zone.
Limnetic zone
69
It is much colder and denses than littoral zone and limnetic zone. Little light penetrates all the way through the limnetic zone into the profundal zone.
Profundal zone
70
Are heterotrophs, means that they eat dead organisms and use oxygen for cellular respinlration.
Fauna
71
It is part of structure of food web, that open water of limnetic zone.
Primary producers
72
Typical FOOD CHAIN in (fish)
Piscivorous fish ↓ Planktivorous fish ↓ Zooplankton ↓ Algae ↓ Nutrients ↑ Benthic Organisms
