Once placed in water‚ the cyst-like eggs hatch within a few hours. The nauplii‚ or larvae‚ are less than 0.5mm in length when they first hatch. Brine shrimp have a biological life cycle of one year‚ during which they grow to a mature length of around one cm on average. This

Ecology Biology Notes GCE Study Buddy Ecology ● Ecology is the study of interactions among organisms‚ and between organisms and the physical and chemical factors making up their external environment ● Ecologists study both the non-living (abiotic) or physical environment‚ and the living (biotic) environment. Physical environment ● Amount of light ○ Light intensity affects the distribution and growth of both plants and animals ● Amount of water ○ Xerophytes are plants which can

As shown in Table 2‚ African Nightcrawlers: BSF Larvae (T3)‚ exhibits pH fluctuations from day 1 onwards. The pH range in this treatment is 6.31 to 8. 43. What is the difference between a’smart’ and a’smart’? Also‚ it exhibits the highest increase in pH over time than other treatments‚ reaching 8.06 by day 21. By the end of the experiment‚ pH levels reached alkaline values‚ indicating a pronounced influence of the combined bioconverter activity on nutrient release and pH dynamics. The highest pH

Integrated Pest Management of palm oil Control of Oryctes rhinoceros Oryctes rhinoceros‚ as has been indicated in the section on zero burning‚ is a severe pest in such replants. A combination of fore-described cultural‚ chemical and biological control is now being used in an integrated manner to successfully manage outbreaks of the pest. Bagworms and Nettle Caterpillars Bagworms and nettle caterpillars are opportunistic pests that can devastate large areas of oil palm if not detected

to gain some knowledge about mealworms and the two different substrates. Mealworms are the larvae of Tenebrio molitor‚ commonly known as the darkling beetle. They are from the kingdom animalia and the class insecta. These mealworms are 1/2” to 3/4” long and have a slightly tough exterior useful for burrowing. They prefer to live in areas where moist organic matter is abundant. The beetles and larvae eat decaying leaves‚ sticks‚ and as composters eat dead insects and stored grains. (CEISO‚ The

Ampang lake and the Gombak river. Biotic factors consist of the living things that shape an ecosystem (Library.thinkquest.org). After examining the lake and river ecosystems‚ we only found two similar biotic components‚ which are the stonefly larvae (Plecoptera) and fish. In Ampang‚ we collected our biotic specimens through sampling macrophytes found in the littoral zone of the lake and over there we found abundant Bladderworts (Utricularia vulgaris)‚ phytoplanktons and leaf litter from riparian
